ISTANBUL—Officials from Russia, Ukraine and the United Nations planned to sign a deal to resume exports of Ukrainian grain via the Black Sea on Friday, Turkish and U.N. officials said, in an announcement that raised hopes of freeing food supplies trapped by the Russian invasion.
U.N. Secretary-General António Guterres landed in Istanbul on Thursday evening, a U.N. official said, adding that the parties involved had come to an agreement but cautioned that last-minute problems could still arise before they sign off on the deal, expected on Friday.
