The AP is reporting 2 dead after what appears to be a suicide bomber attack at the U.S. Embassy in Ankara, Turkey.

This marks the second U.S. Embassy attack in less than 6 months. On September 11, 2012, the U.S. Embassy in Libya was attacked, leaving 4 Americans dead.

The attack, adds to an already tense situation in the Middle East. As conditions continue to deteriorate in Syria, Turkey has become increasingly alarmed, as well as vocal against Syrian President, Bashar Hafez al-Assad. Most recently, Turkey has put into operation several Patriot missiles under NATO command.

In an effort to relieve tensions, Vice President Biden will focus heavily on Syria as he embarks on his European tour. Biden is scheduled to meet with Syrian opposition leader Moaz al-Khatib in Munich, Germany.
