The U.N. humanitarian chief said she was "struck" by the significant devastation she saw in a shattered district of Syria's central city of Homs, AP reported. Valerie Amos told reporters in Damascus on Thursday that the Baba Amr neighborhood in Homs is "completely destroyed." Amos is the first independent outside observer to be allowed in Baba Amr since the military overran the district, wrestling it from opposition control on March 1. She was allowed a brief tour in the ravaged district on Wednesday. She said she found most residents had fled following the bloody military siege. Amos spoke after a meeting with the Syrian ministers of health and education in Damascus.
