“Moscow has suspended its participation in a UN-backed deal with Kyiv that unblocked the movement of Ukrainian grain out of its southern ports, threatening to deepen the global food crisis.

Russia linked its decision to pull out of the deal to an attack on Saturday on ships in the port of Sevastopol in the Crimean peninsula, which Russia annexed from Ukraine in 2014.

It blamed the attack on Ukrainian armed forces, claiming air defences shot down Ukrainian drones but autonomous explosive boats had caused damage to navy vessels and energy facilities.”
