(ANSA) - Rome, September 25 - Two suspected Libyan jihad militants who were thought to have been trying to prepare attacks on Western targets have been deported from Italy, authorities in Rome said Tuesday. The unnamed men, aged 26 and 28, are believed to have wanted to stage a revenge attack for an American-produced film that allegedly ridicules Islam's Prophet Mohammed. The film sparked a wave of violence in the Muslim world and the U.S. ambassador to Libya, Christopher Stevens, and three other State Department employees were killed in an attack by Islamist extremists in Benghazi earlier this month. The deported men are thought to have links to Salafi militia operating in Libya. They had been in Rome for a number of months for treatment on injuries sustained in the civil war that led to the end of Muammar Gaddafi's regime last year and they were staying at hotels in the capital. Investigators said that "they had started activities of proselytism and propaganda for the jihad in the Libyan community to obtain material to carry out attacks against Western interests". The investigators said the pair came under suspicion because of the "radical nature of their behaviour", above all with fellow Libyans.
