Syrian forces advance on IS-held air base

Syrian government forces advanced to within six miles (10 kilometers) of the Islamic State-occupied Tabqa air base in the northern part of the country today, part of a push to try to unseat the extremist group from its de facto capital, Raqqa.
Government forces recaptured the nearby Thawra oil field from IS militants, according to a Syrian journalist Eyad al-Hosain, who is embedded with the army. The Britain-based Syrian Observatory for Human Rights monitoring group said the army advanced to within seven kilometers (four miles) of Tabqa.
The Tabqa base, 45 kilometers (28 miles) from Raqqa, holds strategic and symbolic value in the government campaign on the IS capital. It was the last position held by government forces in the Raqqa province before IS militants overran it in August 2014, killing scores of detained soldiers in a massacre they documented on video. Raqqa itself became the militants' first captive city.

A Syrian opposition coalition, meanwhile, called on Turkey to investigate the deaths of at least eight Syrian refugees, including four children, who were allegedly shot dead by border guards yesterday night while trying to cross the frontier.
A statement by the National Coalition of Syrian Revolution and Opposition Forces accused Turkish border guards of firing at a group of civilians trying to cross from Kherbet al-Jouz in northwestern Syria into Turkey's Hatay province, killing 11 people.
The coalition, which relies on Turkish political and financial support, said the incident "clashes with the generosity displayed by the Turkish government and brotherly people toward displaced civilians."

The Britain-based Syrian Observatory for Human Rights put the death toll at eight. The Local Coordination Committees, an activist network, said at least one of those trying to cross was from Jarablus, a northern Syrian town under Islamic State control.
