At least 21 people were killed Wednesday in clashes with Syrian forces in separate cities throughout Syria, pan-Arab news outlet Al Arabiya reported according to opposition groups.
Earlier Wednesday, Syrian opposition activists said that security forces still had armoured vehicles stationed in city streets ready to act against protesters even though Arab League peace monitors said they had withdrawn.
Opposition groups in the cities of Idlib in the north, central Homs and Deraa in the south said the army had hidden armor in dugouts and replaced tanks with blue armored vehicles said to belong to police forces.
The deaths also come days after the Free Syria Army - a mysterious militant group that has claimed to have over 15,000 army defectors in its ranks - announced a ceasefire pending the visit of Arab League monitors to the embattled nation.
