Clinton says Istanbul attack strengthens resolve to defeat terrorism

(Reuters) - U.S. Democratic presidential candidate Hillary Clinton said on Tuesday the attack on an Istanbul airport was a reminder that the United States "cannot retreat." "Today's attack in Istanbul only strengthens our resolve to defeat the forces of terrorism and radical jihadism around the world," she said in a statement. "We must deepen our cooperation with our allies and partners in the Middle East and Europe to take on this threat." (Reporting by Eric Beech; Editing by Eric Walsh)
