Cairo, Egypt ? The leader of an al-Qaida-inspired group wanted for last month’s bombings at a Red Sea resort was killed in a gunbattle Tuesday.

Nasser Khamis el-Mallahi was the seventh suspected extremist killed by Egyptian security forces in the Sinai following three bombings April 24 in Dahab that killed 21 people.

The Dahab blast was the third major attack on Sinai resorts in the past two years. Egyptian authorities have said all the attacks were carried out by a group calling itself Monotheism and Jihad, led by el-Mallahi.
