A Turkish security guard and a suicide bomber were killed and several more were wounded early Friday in an explosion at the U.S. Embassy in Ankara. Initially the attack was believed to be the work of al Qaeda, but Turkish authorities have now identified the bomber as a member of a left-wing militant group. President Obama called the attack an '"act of terror" Friday, and U.S. officials say they are working with Turkish police. Turkey hosts hundreds of NATO soldiers from the U.S. and elsewhere who are using a Patriot missile defense system along the border with Syria.
