A series of explosions rocked a British army barracks in western England before dawn Monday after two intruders were spotted and soldiers were evacuated, officials said. The IRA claimed responsibility for the attack.

Col. Peter Hicks, a Defense Ministry spokesman, said one soldier was slightly injured by flying glass when three blasts shook the Ternhill barracks, blowing out a wall of one block and igniting several fires.Thirty minutes earlier, a sentry had fired warning shots at two intruders, but they escaped, said Hicks.
