Unknown attackers have fired shots at a security booth outside the U.S. embassy in Istanbul, Turkey—but no one is believed to be injured. Ties between Turkey and the U.S. have come under strain this month over the case of imprisoned American pastor Andrew Craig Brunson. The Trump administration slapped huge sanctions on the country and increased tariffs which sent the Turkish lira into free fall. Ankara governor’s office said six shots were fired from a moving white car towards the embassy compound at 5:30 a.m. Monday local time, with three of the bullets hitting the gate and a window. U.S. Embassy spokesman David Gainer thanked police for their “rapid response” and said no injuries had been reported. The attack was poorly-timed from the attackers' perspective—the U.S. mission is closed this week as Turkey celebrates the Muslim holiday of Eid al-Adha.
