ISLAMABAD: A suicide blast at Tarlai Imambargah on Friday shocked the capital, marking the second big terror attack in less than three months. Despite strict police and administration security, militants struck again. On November 11 last year, a suicide bomber exploded outside the Judicial Complex in G-11. That attack killed 12 people and injured over 36. Authorities responded by setting up police pickets on city roads and narrowing busy streets during rush hours to spot suspicious activity. These strict measures hampered daily commuting but aimed to improve safety. After Friday's attack, relatives searched for missing loved ones at Pims hospital, voicing anger at security failures. A senior police officer explained that the blast happened in a rural area on Islamabad’s outskirts, unlike the urban zones where security is stronger. He said police focus on government buildings and sensitive sites inside the city. The officer added that “human intelligence” is needed to monitor rural areas, which terrorists often use as “safe heavens.” After the November blast, Interior Minister Mohsin Naqvi ordered that no vehicle enter Islamabad without an e-tag within two weeks. Later, Minister of State for Interior Talal Chaudhry and Police Chief Syed Ali Nasir Rizvi made e-tags mandatory for all city vehicles. Authorities put e-tag readers and cameras at 11 to 14 points in Islamabad, linking them to the Safe City system. About 400,000 to 500,000 vehicles use city roads daily, many coming from nearby Rawalpindi. As of February 5, around 203,915 vehicles had e-tags installed, with 19 installation points still active, the capital administration said.
