Bahrain set a two-week ultimatum Thursday for the return of citizens fighting as jihadists abroad, saying they will be charged under the Gulf kingdom's anti-terror laws if they do **t. An interior ministry statement said Bahrainis "currently in conflict zones... on the pretext of jihad" must "return to the country within two weeks". It said it would pursue those Bahrainis fighting abroad, encouraging others to do so or belonging to "extremist religious groups or those considered to be terrorist organisations". Bahrain, headquarters of the US Navy's Fifth Fleet, follows in the footsteps of neighbouring Saudi Arabia, which said last month that its nationals faced up to 20 years in jail for fighting abroad or belonging to "terrorist groups." Riyadh toughened its stance on March 7, listing the Muslim Brotherhood and two Syrian jihadist groups as terrorist organisations, and ordering Saudis fighting abroad to return home within 15 days or face prison.
