Opposition: 'We have become used to such massacres' as death toll surges Opposition group: The tortured bodies of 13 people are found outside a Homs school At least 127 people are killed across Syria on Saturday, opposition activists say Opposition activist: "We have seen people beheaded, children killed, bodies torn apart" Report: The Syrian regime accuses Western and Arab nations of arming the opposition (CNN) -- Reports of horror and carnage continue to mount in Syria, just days before a Tuesday deadline for government forces to withdraw from cities. At least 127 people were killed on Saturday alone, according to the Local Coordination Committees of Syria, a network of opposition activists. At least 59 of those deaths took place in Hama, the LCC said. The group said Syrian forces have been targeting civilians displaced from their homes by earlier fighting. Specifically, the LCC said, the regime is attacking villages and farms around the eastern city of Rastan, where fighting a month ago forced out more than 80% of the city's residents. They escaped to the nearby areas but are now coming under attack, the group said Saturday. Meanwhile, violence broke out in the city of Rastan itself when regime forces fought with defectors at the northern entrance to the city, asid another opposition group, the Syrian Observatory for Human Rights. CNN cannot independently verify reports of violence and deaths, as the government has severely restricted access to international media. The Syrian government has repeatedly said that its forces are fighting armed terrorist gangs. On Sunday, the state-run Syrian Arab News Agency made little mention of any violence but showed images of packed demonstrations that it said took place a day earlier. "Syrian citizens in all the Syrian provinces on Saturday flocked to the main squares to celebrate the 65th anniversary of the foundation of the Baath Arab Socialist Party," SANA said. The participants in the rallies expressed the Syrian people, army and leadership's steadfastness in the face of the conspiracy hatched against Syria. But many reports from inside Syria suggest government forces are slaughtering civilians in an attempt to wipe out dissidents seeking President Bashar al-Assad's ouster. The al-Assad family has ruled Syria for 42 years. One LCC activist in Homs, identified only as Saleem for safety reasons, described a massacre outside a local school that the Syrian army used to launch offensives and detain people. Saleem said the bodies of 13 people, including youths, were found with signs of torture. The truth is we have become used to such massacres. We have seen people beheaded, children killed, bodies torn apart, and nothing surprises us anymore," Saleem said. All we could do is pray to all for help and call on the world to intervene. Months of diplomatic efforts by international leaders have so far failed to stop the bloodshed in Syria. The Syrian government has agreed to pull its forces from cities by Tuesday as part of an deal brokered by Kofi Annan, the former U.N. secretary-general who now serves as the U.N.- Arab League special envoy to Syria. The Syrian government has said it will implement the peace plan. SANA reported Saturday that the government sent two identical letters to the president of the U.N. Security Council and to U.N. Secretary-General Ban Ki-moon, accusing Arab and Western countries of backing the armed groups. In the letters, Syria claimed that "terrorist acts committed by the armed terrorist groups in Syria have increased during the last few days, particularly after reaching an understanding on Kofi Annan's plan," according to SANA. The letters said 2,088 Syrian forces and 478 police officers have been killed. CNN's Salma Abdelaziz and Kamal Ghattas contributed to this report.
