Syrian Troops Shell Homs Area, Red Cross Blocked BEIRUT - Syrian activists say troops are shelling several districts in the rebellious central city of Homs where the government is keeping a Red Cross convoy blocked from reaching thousands stranded in the area. Abu Hassan al-Homsi, a doctor at a makeshift clinic in Khaldiyeh district of Homs says he has treated a dozen wounded. The Local Coordination Committees activist network says mortars have slammed into Khaldiyeh, Bab Sbaa and Khader districts of the city early Saturday. The shelling comes amid a standoff between the government and the Red Cross, which says authorities have prevented its a convoy from delivering badly needed food, medical supplies and blankets to thousands of people still stranded in Baba Amr, the rebel-held district of Homs that was overran by troops Thursday.
