DUBAI (Reuters) -Iran on Saturday executed seven men convicted of killing security personnel and a cleric several years ago, the judiciary’s news agency Mizan reported. Six of the men were ethnic Arab separatists accused of carrying out armed attacks and bombings in Khorramshahr, in the southwestern province of Khuzestan, that killed four security forces. The seventh, Saman Mohammadi Khiyareh, a Kurd, was convicted over the 2009 assassination of Mamousta Sheikh al-Islam, a pro-government Sunni cleric in the Kurdish city of Sanandaj.
