A bomb explosion on Saturday marred the Republic Day celebrations in Manipur, with Governor Gurbachan Jagat appealing for peace in the troubled state.

Amid tight security, Jagat unfurled the national flag and took the salute at an impressive march past by police forces in Imphal.

Separatist rebels triggered an improvised explosive device blast at Wangbal in Thoubal district, police said. No one was injured.

Speaking on the occasion, the governor called for enduring peace in the state.

A Coordination Committee of seven major separatist outfits called for a boycott of the Republic Day.

On Friday, rebels triggered four blasts in the state capital including one at the Manipur Rifles ground. However, no one was injured.
