A boat with Russian, Ukrainian, Turkish and U.N. officials heads to inspect cargo ships coming from Ukraine loaded with grain, in the Marmara Sea in Istanbul, Turkey, Saturday, Oct. 1, 2022. The amount of grain leaving Ukraine has dropped even as a U.N.-brokered deal works to keep food flowing to developing nations, with inspections of ships falling to half what they were four months ago and a backlog of vessels growing as Russia's invasion nears the one-year mark.
