A suicide bomber killed three people and injured six as he blew up his explosives-laden car at a military checkpoint east of Algeria's capital, a local security official said Monday, AP reported. The attack occurred in the Dellys area of Boumerdes, some 50 kilometers (30 miles) east of Algiers, late Sunday during Iftar, the meal that breaks the daily fasting during the Muslim holy month of Ramadan, the official and national media said. There was no immediate claim of responsibility. But most attacks in Algeria are claimed by al-Qaida in Islamic North Africa, a local Islamic insurgency movement that joined Osama bin Laden's terror network in 2006. An officer from the communal guards said two militants attempted to drive into a military barracks but came under heavy fire at a checkpoint. One assailant blew himself up at the checkpoint while the other jumped out of the car, the security official told The Associated Press. The second militant was detained, he said.
