KARACHI - Four out of five victims of the attack on Majlis-e-Aza in Nazimabad were laid to rest on Monday while security agencies have claimed to have arrested as many as 50 suspects in connection with the incident so far. The law-enforcement agencies remain clueless about the group behind the sectarian incident.

Around two dozen more suspects were taken into custody during targeted raids and operations in various parts of the city on Monday.

The areas where the police and Rangers carried out the operation include Moosa Colony, Nazimabad, Khilafat Chowk, Paposh Nagar, Gulshan-e-Iqbal and Shah Faisal Colony. The suspects were later shifted to undisclosed location for further  questioning. But despite these arrests, the law enforcers have still not been able to get to those who were directly involved in the incident.

Syed Zaki Abbas and his three nephews, Baqar, Nasir and Nayyar were gunned down while their driver Nadeem, who belonged to the Sunni sect, also perished in the attack. Besides that half a dozen, including two women, were wounded when gunmen riding a motorcycle had opened indiscriminate fire at the participants of majlis at a house in Nazimabad No 4 on Saturday.

Nadeem’s funeral prayers were offered on Sunday while funeral prayers of other victims were offered at Imambargah, Khair-ul-Ammal, Ancholi Society after noon prayers, which were attended by a large number of people.

After the prayers were over, the participants staged a protest demonstration, and demanded the government launches a crackdown against the banned militant outfits still operating in the city.

The victims were later buried at Wadi-e-Hussain graveyard.

This was the fifth consecutive attack on the Shiite community since the holy month of Muharram began.

In all, at least eight persons have lost their lives in these attacks, including a father, his son and two brothers.

It is worth mentioning here that the law- enforcement agencies have claimed 80 percent decline in crimes following the Karachi operation began on September 5, 2013.

Security agencies have claimed to have arrested more than 30,000 suspected criminals during the operation while conviction rate remains discouraging that shows the failure of criminal justice system of the country.

Police high-ups opine that the operation is completely focused on political parties, and that militant networks operating in the city are not being tackled properly.
