Ukraine has carried out large-scale drone strikes against four airbases deep inside Russia, destroying multiple combat planes, according to a source in the Ukrainian Security Service (SBU).

At least seven people were killed and 69 injured when two bridges were blown up in separate Russian regions bordering Ukraine ahead of planned peace talks.

Ukrainian negotiators at talks scheduled for June 2 in Istanbul will present to the Russian side a proposed roadmap for reaching a lasting peace settlement, according to a copy of the document seen by Reuters.

Two bridges have collapsed in Russia’s western regions bordering Ukraine, killing multiple people and injuring dozens, authorities said.

Top security officials say China and North Korea’s support for Russia in its war against Ukraine has exposed how lines between regions have blurred, and the need for a global approach toward defense.

At least seven people were killed after Russian officials said “illegal interference” caused a bridge to collapse and a train to derail in Russia.
