Opposition forces in Syria killed more than 20 government troops on Wednesday (May 2nd), AFP reported.
The government lost 15 soldiers when opposition fighters ambushed them at dawn in Aleppo province, AFP reported the Syrian Observatory for Human Rights as saying. Two opposition fighters also died in the attack.
Clashes near Damascus killed six other troops.
Also on Wednesday, Syrian army forces shelled and torched activists' homes in eastern Deir ez-Zor province and a civilian was killed in southern Deraa by pro-government gunfire.
Maj. Gen. Robert Mood, head of the United Nations monitoring force in Syria, said, "This is not easy and we are seeing -- by the action, by explosions, by firing -- that the ceasefire is really a shaky one. It is not holding," AFP reported the Norwegian as saying.
Meanwhile, UN peacekeeping chief Herve Ladsous said UN member states had so far offered 150 military observers for the 300-strong planned monitoring force and that Syria had refused visas for three proposed monitors.
