Activists say that Islamic State fighters have shot down a warplane believed to be from the U.S.-led coalition over Syria.

The Britain-based Syrian Observatory for Human Rights says the aircraft was shot down Wednesday near the northern city of Raqqa, the Islamic State group's de facto capital.

The Observatory said the warplane was part of the U.S.-led coalition, adding that the captured pilot is an Arab.

Another group, the Raqqa Media Center, that covers areas under IS control in Raqqa claimed that the pilot is Jordanian.

The U.S.-led coalition has carried out hundreds of airstrikes against IS positions in Syria since Sept. 23.

Saudi Arabia, Jordan, Bahrain and the United Arab Emirates have joined in airstrikes against the extremist group, while Qatar is providing logistical support.
