The authorities in Saudi Arabia have arrested two human rights activists so far this year. Human Rights Watch and Amnesty International said Essam Koshak and Ahmed al-Musheikhis were summoned for questioning by police in Mecca and Qatif last week.<br/><br/>Officials have not disclosed the reasons for the detentions. But HRW said they fit a pattern of ongoing repression against peaceful advocates and dissidents, at least 25 of whom have been convicted since 2011. <br/><br/>Many have been handed sentences as long as 10 or 15 years after being found guilty of charges including breaking allegiance with the ruler, sowing discord, inciting public opinion, setting up an unlicensed organisation and violating the cybercrime law.
