(Adds detail, analyst) ALGIERS, Aug 20 (Reuters) - Two car bombs in Algeria killed at least 11 people on Wednesday, the day after an attack that left 43 dead at a military academy, the Algerian press agency APS said quoting the Interior Ministry. It was the bloodiest week in nearly a year in the OPEC member state, a major oil and gas supplier to Europe which is emerging from more than a decade of conflict with Islamist rebels. There was no immediate claim of responsibility for the bombings on Wednesday at Bouira, 150 km (90 miles) east of Algiers, but they follow a spate of attacks by al Qaeda's north African wing. The news agency said 31 people, including four military personnel, were wounded. All the dead were civilians. The first bomb hit a military area at 6 a.m. (0500 GMT) The second went off near a hotel 15 minutes later, exploding just as a bus passed by carrying workers to a dam construction site, APS said. Most of those who died were travelling on the bus. The bombings appear to mark a tactical shift for militants who had previously specialised in ambushing troops in remote areas. They have also raised questions over official assertions that the militants are a spent force close to being destroyed. David Hartwell, Middle East Editor for Janes Country Risk, said there was a concern that car bombings were being carried out by militants who had trained with insurgents fighting U.S. occupation in Iraq. "That's a real concern for Algerians," he said. "But the group is viewed increasingly as outsiders coming in to attack Algeria. There's no evidence they have more support among the population. This is still a localised thing." Tuesday's bombing was one of the bloodiest incidents in years in the country of 34 million. The target was the gendarmerie training school at Issers, 55 km (34 miles) east of the capital. Violence began in Algeria in 1992 when a military-backed government scrapped elections a radical Islamic party was poised to win. About 150,000 people have died in the ensuing violence. The bloodshed has eased in recent years but a hard core of several hundred rebels fight on as part of Al Qaeda Organisation in the Islamic Maghreb, previously known as the Salafist Group for Preaching and Combat. Since adopting the Al Qaeda name early last year, the group has claimed several attacks including the twin suicide bombings of U.N. offices and a court building in Algiers in December 2007 which killed 41 people. A total of 57 people were killed in bombings within three days last September.
