KYIV, July 17 (Reuters) - Russia halted participation on Monday in the year-old U.N.-brokered deal that lets Ukraine export grain through the Black Sea, spreading fear in poorer countries that price rises will put food out of reach.
Hours earlier, a blast knocked out Russia's bridge to Crimea in what Moscow called a strike by Ukrainian sea drones. Russia said two civilians were killed and their daughter wounded in what Moscow cast as a terrorist attack on the road bridge, a major artery for Russian troops fighting in Ukraine.
The Kremlin said there was no link between the attack and its decision to suspend the grain deal, over what it called a failure to meet its demands to implement a parallel agreement easing rules for its own food and fertilizer exports.
"Unfortunately, the part of these Black Sea agreements concerning Russia has not been implemented so far, so its effect is terminated," Kremlin spokesman Dmitry Peskov told reporters on a conference call.
U.N. Secretary-General Antonio Guterres signalled that Russia's withdrawal meant that the related pact to facilitate Russia's grain and fertilizer exports was also terminated.
"Today's decision by the Russian Federation will strike a blow to people in need everywhere," he told reporters.
Moscow said it would consider rejoining the grain deal if it saw "concrete results" on its demands but that its guarantees for the safety of navigation would meanwhile be revoked.
In Washington, the White House said Russia's suspension of the pact "will worsen food security and harm millions".
GLOBAL FOOD PRICES
Ukraine and Russia are some of the world's biggest exporters of grain and other foodstuffs and any interruption could drive up food prices across the globe, especially in the poorest countries.
Shashwat Saraf, the emergency director in East Africa for the International Rescue Committee (IRC), said the impacts would be far-reaching in Somalia, Ethiopia and Kenya, which have been facing the Horn of Africa's worst drought in decades.
"I don't know how we will survive," said Halima Hussein, a mother of five children living in a crowded camp in Somalia's capital Mogadishu for people displaced by years of failed rains and violence.
Ukraine's President Volodymyr Zelenskiy raised the prospect of resuming grain exports without Russia's participation, suggesting Kyiv would seek Turkey's support to effectively negate the Russian de facto blockade imposed last year.
"We are not afraid," spokesperson Serhiy Nykyforov quoted Zelenskiy as saying. "We were approached by companies, shipowners. They said that they are ready, if Ukraine lets them go, and Turkey continues to let them through, then everyone is ready to continue supplying grain."
BRIDGE BLAST
The blast on the road bridge to Crimea could have a direct impact on Moscow's ability to supply its troops in southern Ukraine, and reveals the vulnerability of Russia's own Black Sea infrastructure to devices such as seaborne drones: small, fast remote-controlled boats packed with explosives.
Images showed a section of the road bridge had come down and traffic was halted in both directions, although a parallel railway bridge was still operational. Blasts were reported before dawn on the 19-km (12-mile) bridge, which Russian President Vladimir Putin ordered built after seizing and annexing the peninsula from Ukraine in 2014.
Putin told officials repair work should start quickly and that Russia would respond to the "senseless" attack.
Kyiv gave no official account of the blasts but Ukrainian media quoted unidentified officials as saying Ukraine's Security Service (SBU) was behind it. SBU spokesperson Artem Dekhtyarenko euphemistically alluded to the idea that the agency would reveal the details of the blast after Ukraine won the war, without directly claiming responsibility.
Ukraine says the bridge is illegal and its use by Russia for military supplies makes it a legitimate target. It was hit by a massive explosion and fire in October.
The grain deal was hailed as preventing a global food emergency when it was brokered by the United Nations and Turkey last year.
Global commodity food prices rose on Monday, though the increase was limited, suggesting traders did not yet anticipate a severe supply crisis.
Turkish President Tayyip Erdogan, the grain deal's sponsor, said earlier on Monday he still believed Putin wanted it to continue.
Western countries say Russia is trying to use its leverage over the grain deal to weaken financial sanctions, which do not apply to Russia's agricultural exports.
European Commission President Ursula von der Leyen described Russia's suspension of the agreement as a "cynical move" and said the EU would continue to try to secure food for poor countries.
U.S. aid chief Samantha Power announced more than $500 million in humanitarian assistance during a visit to Ukraine, where the United Nations says some 17 million people need help following Russia's invasion.
Russian shelling killed two people and wounded 10 in the town of Bilopillia in Ukraine's northern Sumy region near the border with Russia on Monday, police said.
WITHOUT RUSSIA?
Russia has extended the Black Sea deal three times in the past year, despite repeated threats to quit. It suspended participation after an attack on its fleet by seaborne Ukrainian drones in October, leading to a few days when Ukraine, Turkey and the United Nations kept exports going without Moscow.
Denys Marchuk, deputy head of the Ukrainian Agrarian Council, the main agribusiness organisation in Ukraine, said seaborne exports might proceed again without Russian agreement.
"If there will be safety guarantees from our partners, then why not conduct the grain initiative without Russia's participation?" he told Reuters.
Any such resumption of shipments without Russia's blessing would probably depend on insurers. Industry sources told Reuters they were studying whether to freeze their coverage.
"The (key) question is whether Russia mines the area which would effectively cease any form of cover being offered," one insurance industry source said.
The latest blast on Russia's bridge to Crimea follows months of Ukrainian strikes on Russian supply lines as Kyiv pursues a counteroffensive to drive Russian forces out of its territory.
