Turkish President Recep Tayyip Erdogan (R) and Croatian President Kolinda Grabar-Kitarovic shake hands during a joint press conference at the Presidential Palace in Ankara, Turkey, on Jan. 16, 2019. The bomb attack in Syria's northern city of Manbij killed 20 people, including five U.S. soldiers, Turkish President Recep Tayyip Erdogan said Wednesday. The Islamic State (IS) militant group has claimed responsibility for the attack, but the incident is trying to influence U.S. President Donald Trump's decision to pull out from Syria, Erdogan said in a joint press conference with the visiting Croatian president.
