Washington and Baghdad will begin discussions expected to lead to a timeline to reduce the presence of troops from the US-led coalition fighting the Islamic State group, Iraq said Thursday. The two countries agreed to form working groups that would eventually lead to formulating “a specific and clear timeline… and to begin the gradual reduction of its (the coalition’s) advisers on Iraqi soil”, the foreign ministry said. In a statement, the US Defense Department confirmed upcoming meetings to discuss the “transition” of the coalition.
