ANTALYA, Turkey (Reuters) - U.S. Secretary of State John Kerry called for a halt to fighting around the Ukrainian coastal town of Shyrokyne on Wednesday as NATO backed his demand that Russia fully implement a Ukraine ceasefire agreement.

Despite the February truce, shooting has continued around the coastal town of Shyrokyne, near the strategic port city of Mariupol. Kiev fears separatists may try to seize the port to help cement a long-term hold on eastern districts of Ukraine.
