Government forces enter air base in Aleppo, ending two-year IS siege

Syrian soldiers fought their way into an air base in northern Syria on Tuesday and freed military personnel inside, state television said, after a nearly two-year siege by Islamic State insurgents at the facility.

A military source close to the government said the army was working to secure the Kweires air base in Aleppo province, where soldiers and officers have been under attack since 2013.

The victory comes as Russia is circulating a document at the United Nations that calls for drafting a new Syrian Constitution within the next 18 months.
