A Syrian human rights group says authorities have arrested a former member of the banned Muslim Brotherhood who returned home to Syria for a second time after nearly three decades in exile. The Syrian Human Rights League says Issam al-Haj Ahmed al-Dallalo was arrested April 22 even though he received guarantees from the Syrian Embassy in Saudi Arabia where he was living that he would not be detained. The rights group said Sunday that al-Dallalo was able to visit Syria last year without a problem after receiving the same guarantee. The rights group did not give a reason for the arrest of Dallalo, who was one of several members of the banned Muslim Brotherhood movement who fled Syria in the early 1980s. The Syrian government did not comment on the arrest.
