Sharjah24 - Reuters: Ukraine pressed ahead on Sunday with efforts to restart grain exports from its Black Sea ports under a deal aimed at easing global food shortages but warned deliveries would suffer if a Russian missile strike on Odesa was a sign of more to come.

President Volodymyr Zelenskiy denounced Saturday's attack as "barbarism" that showed Moscow could not be trusted to implement a deal struck just one day earlier with Turkish and United Nations mediation.

The Ukrainian military, quoted by public broadcaster Suspilne, said the Russian missiles did not hit the port's grain storage area or cause significant damage. Kyiv said preparations to resume grain shipments were ongoing.

"We continue technical preparations for the launch of exports of agricultural products from our ports," Infrastructure Minister Oleksandr Kubrakov said in a Facebook post.

According to the Ukrainian military, two Kalibr missiles fired from Russian warships hit the area of a pumping station at the port and two others were shot down by air defence forces.

Russia said on Sunday its forces had hit a Ukrainian warship and a weapons store in Odesa with its high-precision missiles.
