At least five civilians were killed by Russian and Syrian government warplanes that targeted Syria's northwest as residents marked the holiday of Eid al-Fitr.

A local source told Anadolu Agency the five people died on Wednesday in air attacks targeting the town of Kansafra and three villages in Idlib.

The UK-based Syrian Observatory for Human Rights war monitor put the death toll at 10, saying two children were among those killed.

Another civilian died in shelling by government forces on the northern Hama countryside, also held by rebels, said the group, which relies on a network of sources on the ground in Syria.

Government air attacks also hit a motorcycle in the Idlib town of Maaret al-Numan, killing a woman and her two children, said the Observatory.

Wednesday's attacks come amid an escalation in violence in the country's northwest that is held by Syria's former al-Qaeda affiliate Hay'et Tahrir al-Sham.

A September deal was supposed to avert a full-out government offensive on Idlib province and adjacent areas, home to about three million people, nearly half of whom have been displaced from other parts of Syria.

But the government and its ally Russia have since late April ramped up deadly air raids and rocket fire on the region, and fighters have clashed on its edges.

The bombardment of Idlib province and neighbouring areas has killed more than 300 people since late April, according to the Observatory.

It also displaced nearly 270,000 people in May alone, according to the United Nations.

A total of 24 health facilities and 35 schools have been hit in the latest escalation, according to the UN's humanitarian office.

Analysts predict that President Bashar al-Assad and his allies will continue to chip away at the area, but not unleash a major assault that would create chaos on Turkey's doorstep.

The conflict in Syria has killed hundreds of thousands of people since it started in 2011 with millions displaced. </s> At least five civilians were killed by Russian and Syrian government warplanes that targeted Syria's northwest as residents marked the holiday of Eid al-Fitr.

Warplanes struck a mosque in the rebel-held village of al-Jinnah, in northwest Syria, killing at least 42 people and wounding dozens, the Syrian Observatory for Human Rights, a Britain-based war monitor, said on Thursday.

The jets struck the village, southwest of Atarib near Aleppo, as the mosque was full of worshippers at evening prayer, said the Observatory, which monitors the Syrian war via a network of contacts across the country.

The Observatory does not know who carried out the airstrike.

The US military said it carried out an air strike on Thursday against al Qaeda militants, killing several, at a meeting location in Idlib province, but it was unclear if it was referring to the attack on Al-Jinnah.

The statement from US Central Command made no mention of civilian casualties.

US government officials told NBC News that it was looking into the reports of a bombed mosque.

The US says that it has photographic evidence that proves its planes did not strike the mosque, which is located about 50 feet from its target.

Syrian and Russian military have also carried out many air strikes in Idlib and Aleppo provinces during the war.

Al-Jinnah is located in one of the main rebel-held parts of Syria, the northwest that includes Idlib province and the western parts of Aleppo province, and its population has been swollen by refugees, UN agencies have said.

Rebels in northwest Syria fighting to oust President Bashar al-Assad also include groups supported by Turkey, the United States and Gulf monarchies.
