Two SMC employees received minor injuries when an improvised explosive device exploded in the building's bathroom, police said.

The SMC is involved in preparing photo-identity cards and revising electoral rolls in the Srinagar parliamentary constituency.

No group has yet claimed responsibility for the blast.
