Syrian activists say at least five people have been killed in the besieged town of Homs today as the weeks-long assault by the Assad regime continues. Activists in Hama, meanwhile, say forces rounded up and shot dead 13 men and boys from one family. The family had the same last name as the commander of the opposition group, the Free Syrian Army, but it was unclear whether they were related. On Thursday, U.N. investigators filed a report naming top Syrian officials believed to have committed crimes against humanity. The United Nations also announced it has named former Secretary-General Kofi Annan to act as a joint special envoy on Syria in conjunction with the Arab League.
