Israeli troops arrested a major West Bank leader of the armed wing of radical Islamist movement Hamas who had been wanted for three years, a Palestinian security official said on Thursday. Omar Tirawi, 40, from the Ezzedine al-Qassam Brigades command in Nablus, was arrested in the cityÂ’s El-Makhfiah neighbourhood in the northern West Bank. Soldiers arrived in about 30 jeeps and surrounded the building where he was hiding. They opened fire into the air but Tirawi surrendered without resistance, the Palestinian security official said. An Israeli military source said soldiers arrested 16 wanted Palestinians in raids across the West Bank overnight.
