Four days after suspending its backing for a United Nations-led safe passage for the seaborne transport of Ukrainian grain, Russia announced on Wednesday that it is returning to the scheme.

The Russian Ministry of Defence said on its website that it had received the guarantees it had been demanding from Ukraine that the corridor would not be used for military purposes.

“The Ukrainian side officially assured that ‘the maritime humanitarian corridor will be used only in accordance with the provisions of the Black Sea Initiative’,” and other related regulations, the ministry said.
