The explosion took place inside the house of BJP leader Jasbir Singh.
"All the injured have been shifted to Rajouri civil hospital for treatment," officials said.
It was not immediately known whether the explosion took place inside the house or some one tossed a grenade inside.
BJP State general secretary Ashok Kaul has condemed the terrorist attack on the party's Mandal President, Rajouri Urban, Jasbir Singh's residence.
"Seven to eight family members are seriously injured. This is a cowardly act that will never be accepted," Mr. Kaul said, in a tweet.
