The bomb in central Damascus killed 13 people on Tuesday, state television said, a day after Prime Minister Wael al-Halki survived an attack on his convoy in the heart of the Syrian capital. State television said 70 people were wounded, several critically. The British-based Syrian Observatory reported 9 dead civilians and 3 security men and said the death toll was likely to rise.
