A truck carrying a suicide bomb exploded Sunday at a security checkpoint in Hama on Saturday, killing at least 30. The state-run news agency Sana blamed the Syrian rebels, while the British-based Syrian Observatory for Human Rights blamed an al Qaeda-linked group, al-Nusra Front. The attack is believed to have targeted government soldiers, although most of those killed were civilians. Hama was once the site of some of the biggest protests against President Bashar al-Assad in 2011, but government forces stormed the city in the summer of 2011 and have maintained control ever since. Meanwhile, the Arab League announced Sunday that the international-led peace talks between Assad and the rebels will begin on November 23.
