Prime Minister Sir Keir Starmer will push allies to provide Ukraine with more long-range missiles to strike Russian targets at a meeting in London on Friday, BBC reported.

He will host Ukrainian President Volodymyr Zelensky along with the so-called "coalition of the willing", comprising of more than 20 of Ukraine's allies who have agreed to provide Kyiv security guarantees once a ceasefire is brokered.

Zelensky has been pleading for weeks for more long-range weapons from the West, a move Russia has warned would escalate the conflict. 

Ukraine's leader is travelling from Brussels, where he met EU leaders on Thursday seeking financial support, according to BBC.
