Sinai-based militants claim responsibility for tourist bus blast in Egypt

CAIRO (Reuters) - The Islamist militant group Ansar Bayt al-Maqdis said on Tuesday the bombing of a tourist bus in Egypt's Sinai that killed two South Koreans and the Egyptian driver on Sunday was a suicide attack carried out by one of its fighters, and threatened more strikes against economic targets.

The attack on the bus, which was travelling to Israel from St. Catherine's Monastery, a popular tourist destination in the south Sinai, was the first assault on tourists since President Mohamed Mursi's ouster spurred an Islamist insurgency.
