Officials from Ukraine and Russia have expressed optimism about the progress of peace talks as the Kremlin continues its assault on Kyiv and other cities.

Russian foreign Minister Sergey Lavrov said neutral military status for Ukraine was being "seriously discussed", while Ukraine President Volodymyr Zelenskyy said Russia's demands were getting “more realistic”.

The Financial Times reports that a 15-point plan aimed at ending the fighting has been drawn up.

The proposals include a ceasefire and Russian withdrawal in return for Ukraine pledging to remain neutral and accepting curbs on its armed forces.

Both sides stressed that the talks remain difficult, with serious differences over what neutrality might look like for Ukraine.

The paper said Ukraine would have to end its bid to join NATO – a move President Zelenskyy has already hinted he would be open to.

It would also have to promise not to allow foreign military bases or weaponry into the country in exchange for protection from allies such as the US, UK and Turkey.

It is believed the status of territories annexed by Russia in 2014 could still be a major stumbling block.

Earlier President Zelenskyy appeared via video-link before US Congress and again appealed for the imposition of a no-fly zone above his country.

Invoking Pearl Harbour and 9/11, he pleaded with America for more weapons and tougher sanctions against Russia, saying: “We need you right now”.
