DAMASCUS, July 9 (Xinhua) -- As many as 20 fighters from the Islamic State (IS), formerly known as the Islamic State in Iraq and the Levant, were killed on Wednesday morning by Syrian airstrikes against the northern city of al-Raqqa, according to the UK-based Syrian Observatory for Human Rights.
The airstrikes targeted a facility of the IS, an al-Qaida breakaway group, which is used as a training camp for its fighters in al-Raqqa, the Observatory said.
Two other people were also killed in the airstrikes, according to the Observatory.
Al-Raqqa fell into the IS last year and is considered the main base for the al-Qaida splinter group in northern Syria.
The IS, which declared recently the establishment of an Islamic State in the areas under its control in Syria and Iraq, also controls large swathes of territories in Syria's oil-rich province of Deir al-Zour on eastern borders with Iraq.
