A video from Deir al-Assafir posted on YouTube featured the bodies of little children on the ground, with adults carrying injured children and women grieving over the torn bodies of their children.
According to opposition groups, Syrian military planes dropped cluster bombs on a playground while the children were playing, in the village of Deir al-Asafir in Damascus suburb.
"None of those killed were older than 15 years old. There are two women among 15 people wounded, mostly hit as they were inside the courtyards of their houses," Abu Kassem, an activist in the village told Reuters.
"There were no fighters inside Deir al-Asafir when the bombing occurred. They operate on the outskirts. This was indiscriminate bombing," he said, adding that the bombs dropped were cluster bombs.
However, there is no official confirmation on the incident and the media is also unable to confirm the reports as Syria has barred most media reporters from the country.
There have been allegations of Syria using cluster bombs to fight the rebels and the U.N. political affairs chief had informed the UN Security Council earlier this month, about credible reports on Syria using such bombs.
However, Syria had denied the allegations saying it did not possess cluster bombs, Reuters has reported.
Intense fighting has been continuing between the Syrian President Bashar al-Assad-controlled government forces and opposition groups in the country. The conflict between the two groups started 20-months ago, as a non-violent protest against the government and has now turned into a full-fledged civil war killing more than 40,000 civilians and forcing 400,000 others to flee the country.
The Syrian government has not heeded to international pressure to stop aerial strikes that is killing the Syrian civilians and has intensified the military operations against the rivals. Government calls the rebels as terrorists and has been claiming that they are “cleansing” the country of terrorist elements.
The war in the country has also spilled over to neighboring countries in the region. Turkey, one time ally of Syria and a NATO member, has requested NATO for support against the Syrian offensive as the shelling from Syrian border killed several of its citizens.
