Military source says more than 160 targets struck in and around ISIL-held ancient city amid separate Yarmouk bombings.

Syrian fighter jets have carried out a series of strikes against the Islamic State of Iraq and Levant (ISIL) group in and around the ancient city of Palmyra, according to a military source.
The source was quoted by the AFP news agency on Tuesday as saying that the Syrian air force struck more than 160 ISIL targets, while state television reported that at least 50 "terrorists" were killed in the attacks.
ISIL captured the historical city on May 22 after a week of battling government forces and forcing them to
 
retreat.
"The air force struck more than 160 Daesh targets, killing and wounding terrorists and destroying weapons and vehicles equipped with machineguns" on Palmyra's outskirts and elsewhere in the east of Homs province, the military source said.
"Military operations, including air raids, are ongoing in the area around al-Suknah, Palmyra, the Arak and al-Hail gas fields and all the roads leading to Palmyra," he said.
But local activists have criticised the government's "indiscriminate" air strikes, saying civilians are bearing the brunt of the attacks.
Syrian state television also reported that at least 140 ISIL fighters have been killed in air strikes on an ISIL military base in al-Raqqa.
'Civilians killed'
The Palmyra Media Centre, a monitoring group on the ground, released a statement on Monday evening condemning the deadly air raids, which they say destroyed numerous residential buildings.
"At least 15 people, including women and children, have been killed and dozens of others injured by the air raids," the group said.
It also accused the government of using ISIL's takeover as a "fabricated pretext to bombard the city and its

people".
The group challenged the government's claim on Sunday that ISIL massacred 400 civilians.
Nasser, of the Palmyra Media Centre, told Al Jazeera that most of those killed were government troopscaptured by ISIL fighters after taking over the town on Wednesday.
"Shabiha [a term used to describe pro-regime militias and supporters], including men and women, were the ones targeted and killed," he said.
Yarmouk bombings
Also on Tuesday, an activist on the ground told Al Jazeera, Syrian government helicopters dropped at least six barrel bombs over the opposition-held Damascus district of Yarmouk, wreaking havoc in residential areas and causing numerous casualties.
Rami al-Sayed, the activist, said that there were also attempts to rescue civilians trapped under the rubble of buildings. Another activist reported that one body had been recovered and at least three people had suffered injuries.
He said that the bombings came amid a barrage of "various types of weapons, including mortar shells, and rockets".
Sayed said the increased attacks coincide with ongoing attempts by Fatah al-Intifada and the General Command, two Palestinian groups which back the Syrian government, to enter the district and seize it from the Nusra Front and its loyalists.
Syrian activists posted video online that purportedly shows destruction caused by the barrel bombs in Yarmouk.
