A Norwegian freelance journalist has been detained in the Yemeni capital Sana’a on suspicion of sping on Iranian-backed Houthi rebels. Raymond Lidal, 28, was arrested in the early morning hours of March 29 by Houthi security forces while taking photos of Saudi-led coalition airstrikes on Houthi rebels from his home, news outlets including CNN reported. News of his detention was not reported for nearly two weeks. Lidal was detained because he was in Yemen on a student visa rather than a journalist visa, Bergens Tidende, a Norwegian newspaper that published Lidal’s work, reported. In an interview Lidal did with a Norwegian newspaper two days before his arrest, according to CNN’s report, he said that the Yemeni authorities “don’t really like journalists without the proper papers…officially I’m here as a student.” http://t.co/DMnXK41Xsn … #freeraymondlidal our write up of Raymond's story — Joe Sheffer (@JoeSheffer) April 11, 2015 Shia Houthi militants entered Sana’a in September 2014 and eventually forced the Western-backed President Abed Rabbo Mansour al-Hadi to flee.

He has worked in Yemen since 2012 as a freelance journalist, and has contributed mainly to Norwegian media outlets including the state broadcaster NRK and Bergens Tidende newspaper.
