In Syria, at least 13 people were killed on Sunday in a fight between government forces and insurgents in the country’s northwest.

The government media said the exchange of a barrage of rockets during the fight also hit a government-run hospital killing five people there.

The insurgents’ fire came amid heightened tensions following days of government fire on villages and towns on the edge of the enclave.

The violence strained a fragile months-old truce negotiated between Russia and Turkey that averted a government offensive on Idlib and surrounding areas, the last major rebel

stronghold in the country.
