Armed gunmen burst into the home of a top Fatah official in Gaza early Friday and kidnapped him, the man's family said, in the first such abduction of a politician since Hamas forces routed their Fatah rivals and overtook the strip in June. Omar Al-Ghoul is an adviser to Salaam Fayad, the Palestinian Authority prime minister appointed to lead the West Bank government after Hamas took control of Gaza. Al-Ghoul is considered a harsh critic of Hamas and has a regular newspaper column in which he frequently attacks the Islamic movement. Al-Ghoul arrived in Gaza from the West Bank on Thursday to attend the funeral of his mother-in law. Around 4 a.m. Friday, armed gunmen in civilian clothes burst into his Gaza home, turning it upside down and seizing Al-Ghoul, his relatives reported. There was no claim of responsibility. Hamas officials were not immediately available for comment.
