An image made available by ISIL on June 30, 2014, allegedly shows a member of ISIL parading with a long-range missile on a street in the northern Syrian city of Raqa.
Syrian war planes bombed positions belonging to the terrorists of so-called Islamic State of Iraq and the Levant (ISIL) group in the northern province of Raqa for a second day on Monday, a monitoring group said.
On Sunday, army planes killed at least 31 ISIL terrorists in an unprecedented wave of aerial bombardment against the group in its Raqa bastion.
The bombing continued on Monday, according to the Syrian Observatory for Human Rights, with at least 14 raids against ISIL positions.
There was no immediate death toll in the renewed bombing.
Three raids targeted the area around the town of Tabqa in western Raqa and four hit near the Tabqa military airport, the only remaining position for army in the province.
The other seven strikes hit sites inside Raqa city, the provincial capital.
The raids involved the use of precision weapons rather than the explosive-packed barrel bombs.
The Syrian raids come as the United States carries out air strikes against the ISIL just across the border in neighboring Iraq.
The US strikes are intended to limit the advance of ISIL terrorists who have seized large swathes of territory in both Iraq and Syria, declaring a faked "caliphate."
The group emerged from Al-Qaeda's one-time Iraq affiliate, but has since broken with that organization and grown into a cross-border terrorist group.
It has been battling rival opposition fighters in Syria since early January, after a backlash because of the group's abuses and crimes against civilians.
