Opposition activists in Syria say more than 200 bodies have been found in Daraya, a town outside Damascus, a day after it was retaken by the Syrian army.
Initially it was reported that 79 bodies had been found in houses and basements, but 122 more were found later in the day.
The army overran Daraya on Saturday after three days of heavy bombardment.
President Bashar al-Assad's forces are accused of mass summary executions.
Due to media restrictions in Syria, it is impossible to independently verify the accounts.
