"There will be a ban on display of arms for next 12 days of Muharram in the city," he said while talking to newsmen Monday after visiting the spot of killing of two boy scouts on duty to volunteer at Numaish Chowrangi on Sunday afternoon.
However, he said that guards of the religious scholars will be exempted from these restrictions.
The Minister said that at least 51 persons have been arrested by the police and rangers and interrogations were underway to arrest the culprits involved the killings.
He said Karachi was the economic hub of the country and some anti-Pakistan elements were involved to disrupt the peace of the city.
"Police and Rangers foiled the conspiracy with joint efforts," he added.
Wassan said that an FIR will also be lodged in this regard and replying to queries said that action will be taken against even the personnel of law enforcement agencies if found guilty.
Later, he also visited Liaquat National Hospital (LNH) to enquire about the health of Ehsan Kohati - a representative reporter of private television channel - who sustained bullet injuries.
The Minister gave him cash compensation of Rs 25,000/- from his own pocket and lauded the services of media persons in the line of duty.
