U.N. Humanitarian Chief Valerie Amos is headed to the Syrian city of Homs after meeting with Syria’s foreign minister in Damascus. Amos said she hopes to pave the way for humanitarian relief workers to evacuate the wounded and deliver supplies. The Syrian government continues to block humanitarian aid to the Homs neighborhood of Baba Amr, which endured a nearly month-long siege before it was claimed by government troops last week. Meanwhile, China, an ally to the Syrian regime, has pulled its workers out of the country due to the violence. The United Nations says more than 7,500 people have been killed since President Bashar al-Assad began his crackdown on the uprising a year ago. Assad said Tuesday he would continue fighting what he called “foreign-backed terrorism.”
