Suicide bombers killed more than 130 worshipers in two Shiite mosques in Yemen's capital Friday, one of the deadliest attacks in the war-torn nation's history.

The bombings could trigger new sectarian violence in the mostly Sunni nation under assault from Shiite rebels known as the Houthis.

Al-Masirah TV, a network owned by the Houthi rebels, said 137 were killed and 345 were injured when four suicide bombers attacked the Badr and Al Hashoosh mosques in Sanaa, the Associated Press reported. A fifth suicide attack at another mosque was foiled in the northern city of Saada, the network said.
