Syrian air raids kill dozens of civilians in north: Monitoring group

BEIRUT (Reuters) - A Syrian air force raid killed at least 59 civilians at a market in a town held by Islamic State in Iraq and Syria militants in northern Syria on Saturday, according to a monitoring group.

The strike on the town of al-Bab, northeast of Aleppo, used barrel bombs, which are steel drums full of shrapnel and explosives, the Syrian Observatory for Human Rights said. Syrian President Bashar al-Assad has denied the air force uses such devices.

Dozens of people were also wounded in the attack, according to the monitoring group, which gathers information from sources on the ground. The town has been the focus of several heavy bombardments by the military since late last year.

A second Syrian air force raid in a rebel-held part of Aleppo killed at least 12 civilians on Saturday, the Observatory said.

The United Nations strongly condemned the bombing, which it said killed at least 70 civilians, citing news reports.

Staffan de Mistura, the UN's special envoy for Syria, said it was "totally unacceptable that the Syrian air force attacks its own territory in an indiscriminate way, killing its own citizens, as it brutally happened today in Aleppo."

"The use of barrel bombs must stop," he added.

State news agency SANA did not report on these raids but, citing a military source, said the armed forces had targeted ISIS in Aleppo province's eastern countryside and hit insurgents on a road running north to the border with Turkey, as well as to the south of Aleppo and within the city itself.

The military has been hit by a series of recent setbacks. Insurgents, including al Qaeda's Syrian wing Nusra Front, celebrated inside the last government-held town in Idlib province on Friday after capturing it the night before, while ISIS has secured its grip on the ancient central city of Palmyra.

In Syria's northeast, clashes erupted between the military backed by allied militias and ISIS to the south and southeast of Hasaka, the Observatory said on Friday, after the al Qaeda offshoot planted a bomb on the edge of the city.

The Observatory said the blast killed a number of pro-government fighters while at least 10 died in subsequent clashes. An ISIS statement posted online described the blast as a suicide attack and said it had killed more than 30 of its opponents.

Hasaka province lies next to ISIS-held territory in Iraq, where the group is back on the offensive after losing the city of Tikrit at the start of the month.

SANA said the Syrian military had foiled an attack on Hasaka and had killed dozens of militants in the province. It said it had been targeting ISIS in the provincial countryside with the help of Kurdish YPG militia. The YPG, which has fought the fiercest battles against Islamic State in the northeast, says it does not coordinate with the Syrian military.
