Turkey has set up a field hospital in Idlib province in war-torn Syria following demands from local doctors.

Idlib, the opposition-held city in the northwest, has been under heavy attack by regime forces loyal to President Bashar al-Assad.

Most recently, 15 people were killed and 20 others wounded when a Syrian fighter jet dropped a 'vacuum bomb' in a residential area on Saturday.

Syrian personnel will be able to provide health support to casualties using materials from the Turkish Red Crescent, the organization's Deputy Director General Mintez Şimşek told Anadolu Agency.

The hospital, with a capacity of 50 beds, has an operating room, intensive care units, ultrasound and x-ray devices.

Şimşek called on international institutions to continue sending aid to Syrians and condemned regime attacks on hospitals: "Assad forces continue to kill regardless of age and sex. Besides, there have been recent deliberate attacks on the hospitals.

"It is a war crime," Şimşek added.

More than 200,000 people have been killed in Syria since the conflict between Bashar al-Assad's regime and opposition forces began in 2011, according to the UN.
