BEIRUT (Reuters) -Tensions over a probe into last year's massive blast in Beirut burst into the worst street violence in more than a decade on Thursday, with six Shi'ites shot dead and gun battles reviving memories of the country's 1975-90 civil war.
Bullets bounced off buildings and people ran for cover during bursts of gunfire which lasted several hours on what was once a frontline in the war. At one school, teachers instructed infant children to lie face down on the ground with their hands on their heads, a Reuters witness said.
