Suicide bombers attacked a pair of mosques Friday in the Yemeni capital, unleashing monstrous blasts that ripped through worshippers and killed 137 people in the deadliest assault yet targeting Shiite rebels who have taken over large parts of the rapidly fragmenting nation. At least 13 children were among the dead. The attacks come a day after intense gun battles in the southern city of Aden, between rival troops loyal to Yemen's former and current president, left 13 dead and forced closure of the city's international airport. The Shia rebels, known as Houthis, swept down from their northern strongholds and seized the capital in September. Allied with ousted former Yemeni president Ali Abdullah Saleh, they now control at least nine of Yemen's 21 provinces. Earlier this year they put Abed Rabbo Mansour Hadi, the western-backed president, under house arrest. Hadi has since fled to the southern city of Aden, where he established a temporary capital and maintains he is still the legitimate president.
