Turkey bolstered security at U.S. diplomatic installations across the country Wednesday after men armed with a pump-action shotgun and pistols shot and killed three Turkish policemen outside the U.S. Consulate in Istanbul, officials said.
Turkish police killed three gunmen in a five-minute gun battle that ensued. Turkish Interior Minister Besir Atalay said authorities were looking for a fourth man, who had driven the others to the consulate and might have been wounded as he drove away from the scene.
The attack was "an obvious act of terrorism," U.S. Ambassador Ross Wilson said at the U.S. Embassy in Ankara, Turkey's capital.
The assault targeted police at a guard post at the entrance to the consulate, which is behind high, white walls on a steep hill that overlooks the Bosporus in the distance. The four attackers drove up with their weapons out of sight, near applicants standing in line for U.S. visas and customers chatting in cafes, witnesses said.
