July 22, 2022: Russia and Ukraine, with mediation by Turkey and the U.N., agree on a deal to unblock supplies of grain stuck in Ukraine’s Black Sea ports, ending a standoff that threatened global food security. The deal expires a year later.

Uncertainty swirled around what could be the first direct peace talks between Moscow and Kyiv in years after the Kremlin held off disclosing who would represent Russia, and Ukraine demanded clarity before deciding on its own actions.

Ukrainian officials say Russia launched more than 100 drones, rejecting calls for a ceasefire as Zelenskyy says he'll "be waiting for Putin" to join him for direct talks in Turkey.
