The SAD and the AAP on Sunday attacked the Congress-led Punjab Government over the grenade attack in Amritsar and alleged that there was a "complete breakdown" of the law and order in the State.
Three persons were killed and 20 injured when two motorcycle-borne miscreants hurled a grenade attack at a religious congregation of over 200 devotees inside a Nirankari Bhawan in Amritsar earlier on Sunday.
Shiromani Akali Dal (SAD) chief Sukhbir Singh Badal claimed that the law and order situation in Punjab had "deteriorated" immediately after the Congress came to power.
He alleged that the Congress Government was "encouraging" elements whose sole aim was to disturb Punjab's hard-won peace.
