A suspected IRA truck bomb tore through the commercial center of Portadown in Northern Ireland on Saturday, injuring six people and causing extensive damage, security sources said.
Police said they had received a warning and the town's main street, where the van was parked outside a bank, had been virtual3ly evacuated when the explosion occurred.
Three of the six people hospitalized after the explosion were police officers.
Several warnings from the Irish Republican Army included one giving a location half a mile from where it went off, police said. But the device had already been spotted and an evacuation was under way.
