A university lecturer was killed in a car bomb blast in Tehran and three people were wounded in another explosion today, Iran's al Alam Arabic language television reported.
Al Alam said the dead person and one of the wounded were nuclear physics lecturers.
State radio said the attackers planted a bomb on each of the teachers' vehicles.
"Majid Shahriyari was martyred and his wife was injured ... Fereydoun Abbasi and his wife were both wounded," radio said.
Iran says its atomic programme is purely peaceful, but suspicions that it is seeking nuclear weapons have led to the imposition of several rounds of international sanctions by the United Nations, the European Union and the United States.
