Four policemen were killed in Jammu and Kashmir's Sopore town on Saturday in an improvised explosive device blast.
The attack targeted a patrol unit of the police in the main market in Sopore. Three shops were also destroyed in the massive explosion.
No terror group has claimed responsibility for the attack so far.
The area was cordoned off and a search operation is underway.
Shops in the market were closed and the area was largely deserted due to a strike called by separatists over the 1993 massacre in which 57 people were killed in firing by security forces.
Jammu and Kashmir Chief Minister Mehbooba Mufti expressed her condolences for the families of those killed.
