Army personnel had a narrow escape on Sunday, when a powerful remote-controlled bomb exploded in Kwakeithel, near here, seconds after their truck crossed the place on the Imphal-Tiddim road. The bomb buried near a tree caused a foot-deep crater.

A manhunt by the police shortly after the blast drew a blank. So far, no underground organisation has claimed responsibility.

Police said the explosion was part of the coordinated violent campaign against the security forces by the United National Liberation Front and the Revolutionary People’s Front.
