A member of an international aid group says fighting between the Islamic State group and Syrian army in the northeastern city of Hassakeh has displaced at least 30,000 people.

Iraq-based Sam Duerden of International Rescue Committee says people in the city need food, water, shelter and medical assistance.

The Islamic State group attacked and captured several government-held neighborhoods of Hassakeh on Thursday. The fighting has continued since then, leaving dozens dead, according to activists.

Duerden said via Skype on Monday that many people are fleeing to nearby villages and towns, adding that there are at least 10,000 who have nowhere to go and are staying in schools or community centers.

State news agency SANA said government air strikes killed large numbers of IS fighters in Hassakeh on Monday.
