Killings were reported at rallies in towns across Syria, including four in Hama shortly after a monitoring team arrived. Two more people were shot in Idlib, another monitors’ destination, as they passed a security checkpoint.
The cities to be visited on Thursday – Deraa, Hama and Idlib – lie along a 450-km (280-mile) arc of revolt from the south to the north of Syria. At its midpoint is Homs, where the monitors’ second day had a controversial start when its Sudanese chief reported seeing "nothing frightening" in an initial tour.
The Arab mission is the first notable international involvement in Syria’s conflict, in which thousands have been killed in a military crackdown on the uprising against 41 years of rule by the family of President Bashar al-Assad.
