The direct attacks on Ukraine’s grain, a key part of the global food chain, followed Kiev’s announcement to defy Russia’s naval blockade of grain-exporting ports. “Unfortunately, the grain terminals of an agricultural enterprise in the Odesa region were hit. The enemy destroyed 100 tons of peas and 20 tons of barleyregional governor Oleh Kiper said on the Telegram messaging app. According to him, two people were injured.

Photos released by the emergency ministry showed burning, damaged buildings that appeared to be warehouses, as well as a badly damaged fire engine.

Russia stated that will consider all ships heading to Ukrainian waters as arms carriers since Thursday, in what Washington called an indication that it may attack civilian vessels. Kiev later responded by issuing a similar warning for ships bound for Russia.

Russia’s Defense Ministry announced on Friday that its fleet in the Black Sea is carrying out military drills by firing rockets at “floating targets” and exercises to seize ships. Moscow’s ambassador in Washington denied any plans to attack ships.
