Russia pounds Ukraine's grain, UN warns of hunger from price rises

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 export ports after Moscow's withdrawal this week from a UN-brokered safe sea corridor agreement.

The UN warned that millions of people in poor countries around the world were at greater risk of hunger and starvation from the knock-on effect for food prices.

"Some will go hungry, some will starve, many may die as a result of these decisions," UN aid chief Martin Griffiths told the Security Council.
