KYIV, Ukraine (AP) Russia unleashed intense drone and missile attacks overnight Wednesday, damaging critical port infrastructure in southern Ukraine, including grain and oil terminals, and wounding at least 12 people, officials said.

The bombardment crippled significant parts of export facilities in Odesa and nearby Chornomorsk and destroyed 60,000 tons of grain, according to Ukraines Agriculture Ministry.

It came days after President Vladimir Putin pulled Russia out of its participation in the Black Sea Grain Initiative, a wartime deal that enabled Ukraines exports to reach many countries facing the threat of hunger.

It also followed a vow by Putin to retaliate against Kyiv for an attack Monday on the crucial Kerch Bridge linking Russia with the Crimean Peninsula, which the Kremlin illegally annexed in 2014.

The Agriculture Ministry, citing experts, estimated it would take a year to restore the damaged facilities. The destroyed grain was supposed to have been loaded onto a vessel and sent through the grain corridor two months ago, the statement said.

Such attacks by Russian terrorists are not only affecting our country but also global stability, Ukrainian President Volodymyr Zelenskyy said during a briefing with the visiting Irish prime minister in Kyiv. He said Ukraine needs more anti-aircraft defense systems to protect the port.

Zelenskyy said his government is trying to find a way to maintain a corridor to keep grain exports flowing despite Russias decision to abandon the deal brokered with the U.N. and Turkey.

The corridor must be secure. In fact, knowing Russia, it wont be safe unless the U.N. starts working very clearly and firmly at the level of the secretary-general, he said.

Agriculture Minister Mykola Solskyi warned that if Ukraine cannot export food, the population of the poorest countries will be on the brink of survival! The price of grain will increase, and not all countries will be able to afford buying agricultural products, which means food prices will significantly rise: flour, cereals, meat.

Wheat prices rose more than 2.5% on Tuesday and nearly 8% on Wednesday amid the attacks in Odesa, a key hub for exporting grain , illustrating jitters in global markets. Wednesdays trading price of $7.23 a bushel still was nearly 80% below last years peak.

German Foreign Minister Annalena Baerbock tweeted that Putin hasnt just blown up the Black Sea Grain Initiative; now he has hit the port city of Odesa with a hail of bombs for the second consecutive night.

In doing that, he is robbing the world of any hope of Ukrainian grain. Every one of his bombs also hits the worlds poorest, she said.
