A homemade bomb strapped to the waist of a terrorist exploded among a crowd of worshipers today as Iranian President Ali Khamenei addressed a weekly prayer gathering at Tehran University, killing the bomber and five other people, Iran's news agency said.
Ten others were injured, but Khamenei was not hurt and continued his sermon, the official Islamic Republic News Agency said.
After the prayer service, Tehran radio broadcast the sound of air raid sirens, urged residents to seek refuge from attacking planes and issued a red alert that lasted for 30 minutes. IRNA said the capital's anti-aircraft batteries opened fire.
There was no immediate word on whether Iraqi planes had attacked Tehran, but the two nations, at war for 4 1/2 years, have been attacking civilian targets deep inside the other's territory for 11 days.
Khamenei's sermon was interrupted for three minutes by the explosion, IRNA said.
Thousands of worshipers on the campus and on nearby streets began chanting "Allah Akbar" ("God is great"), the news agency said.
