Large bang after bomb disposal robot enters van in Northern Ireland's Londonderry

LONDONDERRY, Northern Ireland (Reuters) - There was a large bang and black smoke emerged from an abandoned van in a cordoned off area of Londonderry on Monday after an army bomb disposal robot entered the vehicle, a Reuters witness said on Monday. A police officer at the scene told the witness that the army was preparing to conduct a controlled explosion on the vehicle that was hijacked by three masked men who threw an object in the back before abandoning it. There was a second loud bang at the same vehicle minutes later, the witness said. (Reporting by Padraic Halpin; Editing by Robin Pomeroy)
