UN has expressed deep concern over the fate of thousands of civilians trapped in Raqqa, Syria amid an ongoing battle between the US-supported Syrian Democratic Forces and Islamic State group.

“Conditions inside the city are reported to be extremely dire, with limited access to food, water, and basic services for the 30,000 to 50,000 people who remain trapped in the city,” UN deputy spokesman Farhan Haq said at a briefing Monday.

The US-led forces launched their offensive to capture Raqqa on June 6.
