TEHRAN - Iran's semi-official Fars news agency says the Revolutionary Guard has killed four militants along the eastern border with Pakistan. The Sunday report says the Guard clashed with a nine-member cell of the Jaish al-Adl militant group last week, killing four of them, including their leader. Last week, Guard forces wounded two militants in clashes near the border and confiscated weapons and ammunition. Security forces often clash with drug traffickers in the area, which is along one of the main routes for bringing Afghan opium and heroin to the Persian Gulf and Europe.
