Senior Pentagon officials have arrived in Ukraine to "discuss efforts to end the war" with Russia, the US military has said.

The team, led by US Army Secretary Dan Driscoll, is expected to meet Ukrainian President Volodymyr Zelensky in Kyiv on Thursday when he returns from a trip to Turkey.

Reports began surfacing on Wednesday that the US and Russia had prepared a new peace plan, containing major concessions from Ukraine. Neither Washington nor Moscow has officially confirmed the plan.

Earlier in the day, at least 25 people were killed in a Russian missile and drone attack on Ukraine's western city of Ternopil, officials there said. Russia launched a full-scale invasion of Ukraine in 2022.

In Kyiv, Driscoll is joined by the US Army's chief of staff Gen Randy George, top US army commander in Europe Gen Chris Donahue, and Srg Maj of the Army Michael Weimer.

"Secretary Driscoll and team arrived this morning in Kyiv on behalf of the administration on a factfinding mission to meet Ukrainian officials and discuss efforts to end the war," Army spokesman Col David Butler said in a statement.

Driscoll was pictured meeting Ukrainian Defence Minister Denys Shmyhal on Wednesday.

Driscoll and Gen George are the most senior US military officials to hold talks in the Ukrainian capital since President Donald Trump took office in January.

The Ukrainian authorities have not publicly commented on what issues are being discussed with the Americans.

However, one Ukrainian official told CBS, the BBC's US media partner, that the focus would be on the military situation on the ground - in addition to plans for a possible ceasefire.

The official - who was not named - said: "Presidents Zelensky and Trump have already agreed to stop the conflict along the existing lines of engagement, and there are agreements on granting security guarantees".

It comes as a number of outlets are reporting that the US and Russia have privately drawn up proposals on how to end the war.

Citing people familiar with the matter, Axios, the Financial Times and Reuters reported that the plans call for Kyiv to give up some territories and weapons, as well as to significantly cut Ukraine's Armed Forces.

Trump's special envoy Steve Witkoff and Russian leader Vladimir Putin's envoy Kirill Dmitriev are believed to have been involved in working on the 28-point peace plan.

The BBC has asked the White House and a representative for Witkoff to comment.

Kremlin spokesman Dmitry Peskov appeared to downplay the reports.

"In this case, we have no additional innovations to what we call 'the spirit of Anchorage'," he told Russia's state-run media on Wednesday - referring to the August summit between Putin and Trump in the US state of Alaska.

Any agreements reached during the one-day meeting have not been made public.

President Zelensky has repeatedly ruled out any territorial concessions to Russia.

Kyiv and its Western allies, including the US, have been calling for an immediate ceasefire along the vast front line, but Moscow has ruled that out, repeating demands that Ukraine says amount to its de facto capitulation.

Earlier this month, Russian Foreign Minister Sergei Lavrov said Moscow's pre-conditions for a peace deal - including ceding territory, tough curbs on the size of Ukraine's military and the country's neutrality - had not changed since Putin laid them out two months before the full-scale invasion.

The Home Secretary Shabana Mahmood has hinted that she is thinking of changing how policing in England and Wales is organised.

She told a conference of police leaders "the structure of our police forces, if is, if we are honest, irrational".

Mahmood said "disparities in performance" meant that policing in England and Wales was a "postcode lottery".

Some police chiefs want the number of forces to be reduced. Currently, there are 43 in England and Wales.

The government is expected to publish a White Paper on the future of policing next month.

The home secretary was talking at a conference of police leaders organised by the National Police Chiefs' Council (NPCC) and the Association of Police and Crime Commissioners (APCC).

Last week the Home Office announced that the role of Police and Crime Commissioner (PCC) would be abolished. Mahmood told delegates on Wednesday the position "had not worked".

She told the conference "I was a reformer at the Ministry of Justice. I will be a reformer at the Home Office too."

Mahmood told the delegates - mostly senior officers and Police and Crime Commissioners: "The structure of our police forces is, if we are honest, irrational.

"We have loaded critical functions like the national police air service and vetting onto local forces, drawing attention away from neighbourhood policing.

"We have 43 forces tackling criminal gangs who cross borders, and the disparities in performance in forces across the country have grown far too wide, giving truth to the old store that policing in this country is a postcode lottery."

She said the government's plans would be laid out in a White Paper due in December, saying she wanted to see "that national policing is world class without distracting local forces from neighbourhood policing".

"The detail will follow," she said. She did not stay behind to answer questions.

Some police chiefs favour a reduction in the number of forces. In July, Gavin Stephens, NPCC chair, said: "A smaller number of police forces, supported by a national policing organisation, would enable us to make decisions far quicker and maximise funding to invest in technology and our workforce."

But some local PCCs have opposed the idea of force mergers. Last week the Policing Minister Sarah Jones said the role would be abolished.

PCCs are elected officials, but elections have often had a limited turnout. The role was created by the Conservative-Liberal Democrat coalition government in 2012.

The home secretary said in her speech on Wednesday: "I believe the position of a Police and Crime Commissioner, unfortunately, has not worked.

"Without necessary investment in creating a public profile, too many voters were unaware of the existence of the position, or its occupant."

Police forces are also waiting for the latest funding settlement which is due in early December.

Paul Sanford, Chief Constable of Norfolk Constabulary and Chair of the NPCC Finance Coordination Committee, said: "Policing is in a state of financial distress.

"We are seeing declining financial resilience across all forces."

At least 25 Palestinians have been killed in Israeli strikes across the Gaza Strip, the Hamas-run health ministry has said.

Ten people, including a woman and a young girl, were killed when a ministry of religious endowments building in the eastern Zeitoun neighbourhood of Gaza City was hit, according to rescuers.

The Israeli military said it had struck "Hamas terrorist targets" after it said gunmen had opened fire towards an area where its soldiers were operating in the southern city of Khan Younis, in violation of the five-week-old ceasefire agreement.

There was no immediate comment from Hamas.

The flare-up of violence comes after the UN Security Council passed a resolution that endorsed US President Donald Trump's Gaza peace plan to end two years of devastating war.

Mahmoud Bassal, a spokesman for Gaza's Hamas-run Civil Defence agency, told the BBC that Israeli air, drone and artillery strikes hit several locations in Gaza City and Khan Younis shortly after sunset on Wednesday.

The attacks marked a sharp escalation after several days of relative calm, he said.

The Civil Defence reported that the strike in Zeitoun caused severe damage to the religious endowments ministry's building and surrounding structures, and posted a video showing its rescue workers appearing to find two people buried under rubble.

Photos published by the Anadolu news agency meanwhile showed the bodies of three young children reportedly recovered from the scene.

In a separate incident in Gaza City, one person was killed and several others were wounded when a drone struck a group of people at Shejaiya junction on Salah al-Din Street, Gaza's main north-south road, according to Mr Bassal.

He said another person was killed when a tank shell struck a house belonging to the Balboul family in Shejaiya's Mushtaha Street, which is also in eastern Gaza City.

In Khan Younis, three people were killed and a number were wounded in a strike on a group inside a sports club run by the UN agency for Palestinian refugees (Unrwa), he added.

In a statement, the Israel Defense Forces (IDF) said that "several terrorists opened fire toward the area where IDF soldiers are operating in Khan Younis" earlier on Wednesday.

"This action constitutes a violation of the ceasefire agreement. No IDF injuries were reported," it added. "In response, the IDF began striking Hamas terrorist targets across the Gaza Strip."

Israeli public broadcaster Kan cited a security source as saying the targets of the strikes were the commander of the Zeitoun Battalion of Hamas's military wing, the Izz al-Din al-Qassam Brigades, and the commander of its naval force.

On Monday, the UN Security Council passed a resolution that sought to shore up the fragile ceasefire, which took effect on 10 October.

Member states authorised the creation of a transitional governance body called the Board of Peace, which will be chaired by President Trump, and a temporary International Stabilisation Force (ISF), which will be tasked with ensuring "the process of demilitarizing the Gaza Strip".

Trump hailed the resolution as "a moment of true historic proportion".

A Hamas statement reiterated that the group would not give up its weapons without a Palestinian state, arguing its fight against Israel was legitimate "resistance".

Israel's ambassador to the UN stressed the importance of disarmament, saying that his country would "not stop or let up" until Hamas no longer presented "a threat".

The Israeli military launched an offensive in Gaza in response to the Hamas-led attack on southern Israel on 7 October 2023, in which about 1,200 people were killed and 251 others were taken hostage.

At least 69,500 people have been killed in Israeli attacks in Gaza since then, including 280 during the ceasefire, according to the territory's Hamas-run health ministry.
