Dozens of gunmen, including off-duty policemen, blocked two major roads in the Gaza Strip on Saturday, demanding retribution for the killing of a policeman in a drug bust a week ago, the PA Interior Ministry said. The protesters, who included relatives and former colleagues of the dead officer, demanded that Abbas punish the culprits and restore law and order. They also demanded the resignation of Interior Minister Nasser Youssef, who is in charge of security. On Thursday night, gunmen opened fire at the home of Youssef in Ramallah. Policeman stationed outside the house responded by shooting indiscriminately, seriously injuring two passersby. Abbas decided on Saturday to dismiss the officer responsible for the incident. Sources in the city said the gunmen belonged to Fatah's armed wing, the Aksa Martyrs Brigades.
