Death toll in southwest Syria attacks climbs to 50

Overall, the Syrian Observatory said, more than 150 people were killed during the day, including at least 62 civilians and more than 90 locals who joined in the fight against ISIS.

"This operation comes after the outstanding victories achieved recently by the Syrian Army and its allies in Syria's south", the statement said.

News websites in Sweida alleged that some of the jihadists who took part in Wednesday's attack had been given safe passage out of Yarmuk. In Sweida province, these sit on the eastern and western fringes, and the ISIS has been gaining ground in recent days as rebel forces lay down their weapons under a surrender deal with the government.

"Three bombers with explosive belts targeted Sweida city alone, while the other blasts hit villages to the north and east", said the Syrian Observatory for Human Rights.

A Syrian military source, speaking on condition of anonymity, said government forces established control over the Wadi Saisun area and the Sahem al-Golan dam after fierce battles with the extremists. It said another 45 IS militants were killed in the clashes.

According to local pro-opposition news outlet Suwayda 24, several identity cards of IS fighters killed during Wednesday's attacks on Suwayda province traced them to south Damascus.

"They kidnapped more than 40 people, all of them women or children", Bou Ammar said.

Islamic State lost almost all the territory it once held in Syria previous year in separate offensives by the Russian-backed army and a US -backed militia alliance.

The DFA reminded Filipinos in Syria to "take the necessary precautions following the coordinated attacks by the Islamic State in the province of Sweida".

Since its offensive started in June, President Bashar Assad's forces have retaken territories controlled by the rebels along the Golan Heights frontier and are now fighting militants in the country's southern tip.

At least 41 civilians have been killed in air strikes on the jihadist holdout since July 19, the monitor says. The SNN said the militants sneaked into the villages under the cover of darkness, shooting residents as they slept.

Syria's southwestern Quneitra province includes the Syrian Golan Heights, on the border of the territory held by Israel.

More than 350,000 people have been killed and millions displaced since Syria's war started in 2011 with the brutal repression of anti-government protests.

The Islamic State group posted no death toll for its own men in Wednesday's fighting.
