(CNN)- A
barrel bomb killed at least 15 people, including children, in one of
two deadly attacks Thursday in the Syrian city of Aleppo, two groups
monitoring the situation say.
There
was a discrepancy in the number of children reported killed in the
airstrike in the rebel-held Bab al-Nayrab neighborhood. The activist
group Aleppo Media Center reported five children were among the dead;
the UK-based Syrian Observatory for Human Rights said 11 children had
died.
The
AMC posted several harrowing videos online following the barrel
bombing, including one showing two boys covered in dust, desperately
clinging to each other and crying after learning their brother had died.
Amnesty
International says barrel bombs are a common tactic of the Syrian
regime. The strikes came amid Russia's agreement to a 48-hour ceasefire
and the United Nations' emphasis on a need for one.
The
group also reported eight people were killed Thursday, including two
children, when rebels fired mortar rounds into regime-held areas in
western Aleppo.
Last
week a video posted by the Aleppo Media Center captivated the world and
was another stark reminder of the toll of the war in Syria. It showed a
boy, Omran Daqneesh -- no older than five years old -- bloodied and covered with dusk, sitting silently in an ambulance awaiting help after his family's house was destroyed by an airstrike
