A large Turkish-military convoy rumbled into rebel-held areas of northwest Syria on Sunday, witnesses on the ground and activists said. Separately, airstrikes on a rebel-held village in Syria's northwest killed at least seven-people, opposition activists said. Elsewhere, rebel shelling killed a woman and wounded at least three-journalists, Syrian-state TV reported. Relations between Turkey and Syria have deteriorated sharply since Syria's civil-war began in 2011.
