More than two million people in Syria’s Aleppo are in danger of coming under total siege, the United Nations has warned, calling for immediate access to the heavily bombed city.

 

Ferocious fighting has rocked divided Aleppo in recent weeks, with rebels and regime forces seizing rival access routes and cutting off residents.

 

In a statement Monday, the U.N.’s top humanitarian official in Syria, Yacoub El Hillo, and regional coordinator Kevin Kennedy called for a “humanitarian pause” in the hostilities.

 

Two million people in the city are living in fear of besiegement, including up to 275,000 people trapped in east Aleppo, the statement said.
