Syria's Al-Qaeda affiliate abducted two of the country's most prominent media activists from a radio station in the northwestern Idlib province on Sunday, opposition officials told AFP.

"Al-Nusra Front kidnapped at 0655 (0455 GMT) activists Hadi al-Abdallah and Raed Fares in the offices of Fresh FM where they work and live in Kafranbel," said Soner Taleb, head of media at the Syrian National Coalition.

Fares, Fresh FM's director, has previously been detained by Al-Nusra fighters, who disapprove of what they term the station's "secular tendency and support of apostates", Taleb said.

According to a statement published by Fresh FM, Al-Nusra fighters stormed the radio station and confiscated its broadcasting and technical equipment as well as its electricity generators.

Al-Nusra fighters then arrested both Fares and Abdallah, the statement said.

Fares is widely known as the creator behind the often humorous protest posters of Kafranbel, written in English and Arabic and widely circulated online.
