DUBAI (AFP) - More than 40 Bahraini women were arrested and beaten by security forces for protesting against parliamentary by-elections, the main Opp group Al-Wefaq said in a statement Monday. "More than 40 women were arrested... in a commercial centre where they were beaten," it said. "Seven minors aged between 12 and 15 were among them," the statement said, adding that they were "beaten and humiliated." Al-Wefaq said the women had only been expressing their "right to freedom of expression," and called their treatment "savage and inhumane."
