Coalition airstrikes pound IS stronghold in Syria
A rebel fighter stands on a tank near the frontline in the village of Ratyan in the countryside north of the Syrian city of Aleppo on February 19, 2015. Fierce clashes are raging between rebel forces and government troops in the villages of Ratyan and Hardtaneen as regime forces cut the main rebel supply line into Aleppo. The Syrian regime is ready to suspend aerial bombardment of Aleppo to allow a humanitarian ceasefire, a UN envoy said, even as government troops sought to encircle embattled rebels.

The U.S. will provide some moderate Syrian rebels with trucks equipped with machine guns and radios to call in U.S. airstrikes. WSJ's Julian Barnes reports.

FILE - In this Monday, Oct. 20, 2014 file photo, thick smoke and flames from an airstrike by the U.S.-led coalition rise in Kobani, Syria, as seen from a hilltop on the outskirts of Suruc, at the Turkey-Syria border. For a force that has built its reputation on projecting an aura of momentum and invincibility, the prolonged stalemate in Kobani is a setback for Islamic State militants with potential implications in terms of recruitment and support. Nearly two months after it launched its lightning assault on the small Kurdish town, the group is bogged down with an increasingly entrenched and costly battle in which hundreds of its fighters have been killed and a good deal of its military apparatus destroyed.

BEIRUT (AP) - U.S.-led coalition warplanes carried out as many as 30 airstrikes overnight against Islamic State militants in and around the group's de facto capital in northeastern Syria, activists said Sunday.

The Britain-based Syrian Observatory for Human Rights said the strikes targeted IS positions in the city of Raqqa as well as the Division 17 air base, which the militants seized earlier this year from government forces.

The monitoring group, which relies on a network of activists inside Syria, reported at least 30 coalition strikes in all. The Local Coordination Committees, an activist collective, also confirmed the airstrikes. Neither group had casualty figures.

There was no immediate confirmation from the U.S. military.

The American-led coalition began targeting Islamic State militants in Syria in September, expanding an aerial campaign already hitting the extremist group in Iraq.
