At least 13 people died in a car bombing at the Turkey-Syria border, while a main Syrian activist group said 110 people were killed across the country on Monday, according to dpa. The Britain-based Syrian Observatory for Human Rights said the opposition fighters seized control of the key Euphrates dam, and activists in Damascus said the Syrian Free Army managed to take over a base housing the elite presidential guard. The attack at the Cilvegozu-Bab al-Hawa border crossing in Reyhanli, a district in Turkey's Hatay province, killed three Turkish nationals and 10 citizens, Turkish Interior Minister Muammer Guler said. He said 27 people were wounded, 19-20 vehicles were damaged at the scene, according to the Anadolu news agency. A minibus with Syrian license plates was used.
