Russia hits Ukraine's grain for fourth day, practises seizing ships
KYIV, July 21 (Reuters) - Russia pounded Ukrainian food export facilities for a fourth day in a row on Friday and practised seizing ships in the Black Sea in an escalation of what Western leaders say is an attempt to wriggle out of sanctions by threatening a global food crisis.
The attacks on Ukraine's grain, a major part of the global food chain, followed a vow by Kyiv to defy Russia's naval blockade on its grain export ports following Moscow's withdrawal this week from a UN-brokered safe sea corridor agreement.
