Key Points
- Two Russian ballistic missiles hit the centre of the northern Ukrainian city of Sumy on Sunday.
- The attack killed 34 people and wounded 117 in the deadliest strike on Ukraine this year, officials said.
- US President Donald Trump has been trying to broker a ceasefire deal between Russia and Ukraine.
But experts believe that the path to ending a war that’s dragged on for more than three years and killed thousands remains unclear.

What’s blocking a ceasefire between Russia and Ukraine?
“The Putin regime shows absolutely no indication of wanting to de-escalate their attacks. On a day of religious significance for Christians, Palm Sunday, the Russian military unleashed two ballistic missiles on downtown Sumy.”
Matthew Sussex is an associate professor at the Australian National University’s Strategic Defence Studies Centre who specialises in Russian security and defence policy.

He said that Trump’s “desire to be liked by dictators like Putin is standing in the way of a peace deal”, as is the fact the US “does not understand how to treat Russia” and should be forcing it to agree and make concessions.
Is Trump’s negotiation style helping or hindering a ceasefire?
“If there is a ceasefire, I would expect it to be fairly partial, fairly temporary and broken by both sides virtually straight away,” he added.
Ukraine has demanded the release of all prisoners and civilian detainees and expressed a desire for security guarantees from Russia and territory concessions, all of which have been rejected at peace talks.
How are Russia and Ukraine placed to continue the fight?
Sumy has been under increasing pressure since Moscow pushed back many of Ukraine’s troops from its Kursk region inside Russia, across the border.
