At least 91 people, including 15 children and eight women, were killed Monday in attacks across Syria the opposition said were conducted by government forces. The Syrian Network for Human Rights said Syrian regime forces staged air and land offensives that killed 41 people in Damascus and its suburbs, 25 in Aleppo, 11 in Homs, four in Deir az Zor , three in Daraa and Hama each, two in Quneitra, and one each in Idlib and Rakka. The Syrian Network for Human Rights, based in Britain, tracks civilian and dissident casualties. The Syria Local Coordination Committee, another opposition organization, said regime forces used howitzer and rockets on some of the cities. The LLC also reported troops loyal to President Bashar Assad used warplanes to bomb several regions under rebel control, the Andalou news agency reported. Syria's official news agency, SANA, reported security forces neutralized several armed groups during the operations and destroyed tunnels used by opposition forces. The United Nations estimated more than 100,000 people have died in the civil war that began in March 2011 as peaceful anti-government protests.
