By Nidal al-Mughrabi GAZA, Jan 3 (Reuters) - Unknown gunmen shot and killed a militant loyal to Palestinian President Mahmoud Abbas's Fatah faction in northern Gaza on Wednesday, local residents said. Fatah sources blamed militants from the governing Hamas Islamist movement for the shooting, the latest bout of internal violence to hit the Gaza Strip. Hamas officials were not immediately available to comment. Local residents said the victim was on a rooftop in the town of Beit Lahiya with other Fatah gunmen when he was shot. Fatah and Hamas declared a truce in December to end weeks of deadly violence which escalated into running street battles in Gaza after Abbas called for early parliamentary and presidential elections to break a political deadlock with Hamas. Hamas condemned Abbas's move as a coup to oust it less than a year after it surprised Fatah to win a parliamentary ballot. On Monday, militants from both parties were seized, then freed, in separate abductions that sparked fresh clashes. While Abbas has called for fresh elections, he has left the door open to talks with Hamas on forging a unity government that Palestinians hope will lead to the lifting of Western sanctions imposed on the Hamas administration. Abbas has not set a date for elections. Hamas says early polls would be illegal. On top of the internal chaos, general law and order has deteriorated in Gaza in recent months. Palestinian colleagues of a Peruvian photographer abducted by gunmen this week demanded his release on Wednesday, saying the 50-year-old's life was in danger because he needed medicine for heart disease. Sakher Abu El-Awn, Gaza office manager of the French news agency Agence France-Presse, said Jaime Razuri, who was seized outside the AFP Gaza City office on Monday, was taking several types of medication, including for the heart problem. "We believe his life is at serious risk and we urge his captors to release him immediately," Abu El-Awn told Reuters. Razuri's kidnapping is the latest in a spate of abductions of foreign journalists and aid workers in Gaza in the past year. All have been freed unharmed, most after one or two days in captivity. No one has claimed responsibility for Razuri's abduction.
