ISTANBUL
Forces of Bashar al-Assad killed 81 people during the operations they held in the last two days.
The Syrian Revolution General Commission (SRGC) stated on Monday that 81 Syrians had been killed during heavy clashes which broke out in Damascus, Idlib and Homs on Sunday and Monday.
Meanwhile, the operations of al-Assad's forces are still continuing in 323 different places across Syria.
Opponents are being arrested, and civilians are being bombed by tanks, according to sources.
More than 14,000 people, the majority of them civilians, have died since the Syrian uprising began in March 2011, according to the Observatory, including more than 900 killed since the truce came into effect.
UN-Arab League Special Envoy to Syria Kofi Annan presented a peace plan in March. The six-point peace plan includes demands for a ceasefire, the immediate withdrawal of heavy armor from residential areas and access for humanitarian aid.
The plan was presented to Syrian President Bashar al-Assad on March 10 and accepted by him on March 27.
The ceasefire came into effect on April 12, but although the overall level of violence has dropped since then, al-Assad's government has been accused of failing to abide by key terms of the truce plan, including pulling all forces from urban areas and allowing peaceful demonstrations.
The number of UN monitors in Syria has increased to 212. All 300 monitors are due to be deployed by the end of the month.
