Bahrain: 6 opposition leaders arrested after crackdown

After a crackdown in Bahrain, six opposition leaders were arrested, a day after its forces moved in to end weeks of pro-democracy protests that have sucked in troops from its fellow Sunni-ruled neighbour and prompted the king to declare martial law.The leader of Bahrains largest opposition group has urged Saudi Arabia to withdraw its forces and called for a UN inquiry into a crackdown on mainly Shiite protesters that have raised tensions in the oil-exporting region.Three protesters died in the crackdown but so did three policemen mown down by demonstrators in fast-moving cars. The crackdown has drawn sympathy protests from Shiites across the Gulf Arab region, including the worlds top oil Saudi Arabia, and Iran has complained to the United Nations. Iran, which supports Shiite groups in Iraq and Lebanon, asked countries in the region to join it in urging Saudi Arabia to withdraw troops from the Gulf Arab island state.
