Egypt has released Al-Jazeera journalist Mahmoud Hussein after more that four years in detention on accusations of publishing false news, a security source said Friday. Hussein, an Egyptian national held under preventive detention since December 2016, was released from jail Thursday night, the source said, without giving further details. Al-Jazeera has run a daily campaign for his release repeatedly said he was being held without formal charges, a trial or conviction. str-mon/hkb/hc
