Three Spanish freelance journalists who went missing in Syria last year and were believed to have been kidnapped have been released, the Spanish Press Federation and the government say.Antonio Pampliega, Jose Manuel Lopez and Angel Sastre disappeared last July while working on an investigative report in the northern city of Aleppo, where other journalists have been captured in the past, Spanish media reported at the time.The government said a plane brought them from Turkey to Spain on Sunday.No details were immediately available on how the three were released, but their release had been ‘possible thanks to the collaboration of allies and friends especially in the final phase from Turkey and Qatar’, the Spanish government said in a statement.Qatar’s state news agency said Assistant Secretary of State for Foreign Affairs Sultan bin Saad Martian had received a phone call from Spain’s minister of state for foreign affairs, Ignacio Iapanaz Rebeo, thanking ‘the State of Qatar for its efforts in the release’.Various Spanish media, including El Pais, said the three were held by al-Qaeda’s Syrian wing, al-Nusra Front.Qatar has previously mediated the release of foreign hostages held by al-Nusra in Syria.The journalists had entered Syria from Turkey on July 10 and went missing shortly afterwards, Spanish press association FAPE said last year.According to the Syrian Observatory for Human Rights monitoring group, the three reporters were last seen in a rebel-held area of Aleppo on July 13, when they were travelling in a van together before being taken away by armed men.After they disappeared, Madrid said officials were working with Spanish intelligence members in Syria to try and secure their release.
