Turkish President Tayyip Erdogan and U.S. President Donald Trump agreed in an overnight phone call on joint action against Islamic State in the Syrian towns of Raqqa and al-Bab, both held by the militants, Turkish presidency sources said on Wednesday. U.S.-Turkish differences during former President Barack Obama's administration impeded the U.S.-led campaign against Islamic State, and closer coordination could mean faster progress towards freeing swathes of northern Syria from IS.
