One of at least four airmen captured by Al Qaeda militants after their Syrian Air Force helicopter crash-landed has appeared in a new propaganda video that calls for the release of a radical cleric . The pilot , who was captured near Jabal al-Zawiya in Idlib province , is seen looking dazed with bandages wrapped around his head as notorious jihadi Abdullah al-Muhaysini rants alongside him while wielding a massive knife and an assault rifle . Al-Muhaysini , who has long been affiliated with Al Qaeda-linked groups in Syria , suggests the life of the airman will only be spared if the Syrian regime releases notorious jihadi Abu Mus'ab as-Suri , who is wanted in Spain for suspected links to the 1985 El Descanso and 2004 Madrid bombings . Scroll down for video . Fear : The captured pilot is seen looking dazed with bandages wrapped around his head as notorious jihadi Abdullah al-Muhaysini rants alongside him while wielding a massive knife and an assault rifle . Threatened : The pilot , who was captured near Jabal al-Zawiya in Idlib province yesterday , appeared in the video released by Al Qaeda-linked militants from Jabhat al-Nusra this morning . The video shows the airman looking dazed as he sits on the floor of a darkened room with the notorious black and white banner of Al Qaeda 's Syrian affiliate Jabhat al-Nusra behind him . Clearly suffering injuries as a result of the helicopter crash , the pilot still has bloodied bandages wrapped around his head . The footage is decidedly amateur , is clearly filmed on either a mobile phone or a cheap recording device - making it look nothing like the slick , professionally edited videos put out by Nusra 's rival jihadi group Islamic State . Nevertheless , the sight of Al-Muhaysini standing over the pilot and ranting about his possible murder while wielding a large knife has the same chilling impact as any ISIS release . Al-Muhaysini 's primary demand is that the Syrian regime release Abu Mus'ab as-Suri - a notorious Al Qaeda linked militant who was arrested in Pakistan in 2005 and later rendered to his homeland . Aleppo-born As-Suri - who holds Spanish citizenship remains a wanted man in Spain on suspicion of taking part in the Islamic Jihad Organization 's 1985 bombing at Madrid 's El Descanso restaurant , which left 18 dead . He is also wanted as a possible witness to the Al Qaeda-inspired coordinated bombings on the Madrid 's train system , which killed 191 people and left more than 2,000 injured in March 2004 .

The airman was one of six people on board the Syrian Air Force helicopter when it crashed in a rebel-held area of north-western Syria , near Jabal al-Zawiya in Idlib province yesterday . It experienced a technical malfunction and made an emergency crash-landing according to the UK-based Syrian Observatory for Human Rights . Syria 's state news agency confirmed that a helicopter had crashed after a mechanical problem and said the authorities were looking for the crew . The SOHR stated that opposition fighters , including from the Al Qaeda-affiliated Nusra Front , had taken four crew members prisoner . Another airman survived the crash but was reportedly killed by his captors , and the fate of a suspected sixth airman is unknown , the Observatory said . SOHR head Rami Abdel Rahman said : ‘ A regime helicopter was forced to land in the region of Jabal al-Zawiya in the north-west , which is a bastion of ( Al-Qaeda 's Syrian affiliate ) Al-Nusra Front . ‘ Four of the crew were captured and a fifth man was killed by armed men in a neighbouring village. ’ Down : The airman was one of six people on board the Syrian Air Force helicopter when it crashed in a rebel-held area of north-western Syria , near Jabal al-Zawiya in Idlib province yesterday .

Mr Rahman said two of the servicemen were being held by Nusra Front , while the other two were captured by an unknown Islamist group . An amateur video posted online showed rebels inspecting the wreckage of the helicopter , which had rolled on to its side on a rocky hill . The aircraft 's blue undercarriage was partially torn and the nose badly damaged . Photographs posted by activists online showed the same crash site and at least two airmen in rebel custody . The United Nations claims the Syrian air force uses helicopters extensively to drop barrel bombs in indiscriminate attacks on residential areas . The improvised munitions are giant canisters packed with hundreds of pounds of explosives and scrap metal . However , Syrian President Bashar al-Assad denied in a BBC interview last February that his forces used barrel bombs .
