At least 61 civilians have been killed by Syrian regime forces since delegations from Syrian regime and opposition gathered in Geneva for UN-sponsored talks aimed at resolving the five-year conflict.
In a Tuesday statement, the Syrian Network for Human Rights said the fatalities included 14 children and 19 women who were killed in attacks by regime forces and its allies.
According to the London-based group, the highest number of fatalities was reported in the northern city of Aleppo.
Syria has remained locked in a vicious civil war since early 2011 when the regime of Bashar al-Assad cracked down on pro-democracy protests with unexpected ferocity.
Since then, more than 250,000 people have been killed and more than 10 million displaced, according to figures released by the UN.
