KYIV, Aug 16 (Reuters) - A container ship set off from Ukraine's Black Sea port of Odesa on Wednesday in a test of Russia's threat to attack shipping after it abandoned a deal last month allowing Ukraine to export grain.
The departure of the Hong-Kong-flagged Joseph Schulte, which had been in the port since Feb. 23, 2022 - the day before Russia's invasion - followed a new Russian attack on Ukraine's grain export infrastructure.
Russian air strikes damaged grain silos and warehouses at one of the Danube river ports, the governor of the Odesa region said, releasing photos showing destroyed storage facilities and piles of scattered grain and sunflowers.
Governor Oleh Kiper said it was a key facility for grains shipments and the president's chief of staff Andriy Yermak named the port as Reni. There was no immediate comment from Moscow. An industry source said the port was continuing operations.
Benchmark Chicago wheat futures were up about 1% after the news broke on Wednesday morning, adding to a slight earlier gain as they recovered from a two-month low on Tuesday.
Russia has made regular air strikes on Ukrainian ports and grain silos since pulling out of the U.N.-backed deal in mid-July and has threatened to treat any ships leaving Ukraine as potential military targets. On Sunday it fired warning shots at a ship travelling towards Ukraine.
Despite the threats, Ukraine last week announced a "humanitarian corridor" in the Black Sea to release cargo ships that have been trapped in its ports, pledging full transparency to make clear they were serving no military purpose.
"A first vessel used the temporary corridor for merchant ships to/from the ports of Big Odesa," Deputy Prime Minister Oleksandr Kubrakov said on Facebook.
Bernhard Schulte Shipmanagement (BSM), which owns the ship jointly with a Chinese bank, confirmed that the ship was en route to Istanbul.
The ship was carrying more than 30,000 metric tons of cargo in 2,114 containers, Kubrakov said, adding that the corridor would primarily be used to evacuate ships stuck in the Black Sea ports of Chornomorsk, Odesa and Pivdennyi since Russia's invasion.
Moscow has not indicated whether it would respect the shipping corridor, and shipping and insurance sources have expressed concerns about safety.
Ukraine is a major grain and oilseeds exporter and the United Nations says its supplies are vital to developing countries where hunger is a growing concern.
