AMMAN - Troops and militiamen loyal to Syrian President Bashar Al Assad entered a residential district of the city of Homs after six days of tank bombardment that killed scores of people and wounded hundreds, residents and activists said on Monday. Army defectors who had taken refuge in Bab Amro and helped defend the residential district, which has seen regular street rallies against Assad's rule, have withdrawn. Loyalist forces entered the district overnight, they said.
