Russian Air Strikes Rock Ukraine After Grain Deal 

Ukraine says unprecedented air attacks had rocked its capital and other areas, a day after it reached an agreement with Russia to extend a deal allowing grain exports across the Black Sea. <br />The deal, a rare example of cooperation between the warring sides, was welcomed by the United Nations and the United States, though both called for more certainty over the exports as Russia has threatened to end the pact, which is crucial to global food security. <br />But doubts about the viability of the deal were quickly raised after Ukraine accused Russia of launching an extraordinary series of air attacks on Kyiv and other regions.
