A powerful car bomb exploded outside a district court in Pakistan’s capital on Tuesday, killing at least five people and injuring 13 others, state-run media reported.

According to Pakistan Television (PTV), most of the casualties were passersby or individuals arriving for court hearings. The blast also damaged several vehicles parked outside the court, which is normally crowded with visitors.

Witnesses described scenes of chaos following the explosion. Emergency teams, including police and paramedics, rushed to the site, transporting the injured to nearby hospitals. The force of the blast shattered windows and left debris scattered across the street.

Islamabad police have not yet issued a detailed statement but confirmed that investigations are ongoing. Authorities have cordoned off the area and deployed security personnel while forensic teams assess the scene.

No group has claimed responsibility for the attack. The incident comes amid a period of heightened security concerns in the country, following a recent increase in militant activity in some regions.

Officials said a joint team from Islamabad Police, the Counter-Terrorism Department (CTD), and intelligence agencies is investigating the blast to determine its cause and identify those responsible.

The death toll from Monday evening’s car explosion near the historic Red Fort has risen to 13, with more than 30 others injured, authorities confirmed on Tuesday.

The blast struck a busy area in Old Delhi, a major tourist and commercial hub, sending thick smoke and debris into the streets. Several vehicles were set ablaze, windows shattered, and bystanders caught in the blast suffered severe injuries.

Delhi police said the explosion occurred around 6:42 p.m. local time when a slow-moving car stopped near a traffic light outside the Red Fort. Emergency services responded immediately, extinguishing fires and transporting the wounded to nearby hospitals.

Relatives of victims described harrowing scenes at hospitals, with some having to identify their loved ones among the casualties. One man told local media that his nephew, an e-rickshaw driver, was killed in the blast.

Prime Minister Narendra Modi, speaking from Bhutan, called the attack “horrific” and vowed that those responsible would be brought to justice. Defense Minister Rajnath Singh assured the public that the findings of the investigation would be made public once available.

The Red Fort will remain closed to visitors for three days to allow investigators to conduct a thorough probe. Lal Qila Metro Station has also been temporarily shut, and the Chandni Chowk market is closed as authorities review security measures.

A joint investigation is underway, led by Delhi police, the National Security Guard, the National Investigation Agency, and forensic teams. Authorities have not yet determined the cause or identified the perpetrators, though the incident is being treated as a deliberate attack.

Security has been heightened across Delhi and neighboring states, with increased patrols at government buildings, heritage sites, and transportation hubs. The US embassy has advised Americans in the city to avoid the area and large gatherings.

Monday’s blast, one of the deadliest in Delhi in recent years, has left the city on high alert as investigators continue their work.

At least eight people were killed in an explosion near the landmark Red Fort in a densely populated district of the Indian capital New Delhi, city police said.

The blast occurred in a car near the Red Fort, but the exact cause was not immediately known, and was being investigated, city police spokesperson Sanjay Tyagi said, Reuters reported.

At least 11 people were injured, TV channels said.

Visuals on local media showed flames and smoke billowing from more than one vehicle in what was described as a congested street located near a metro station in the old part of Delhi.

At least six vehicles and three autorickshaws caught fire, Delhi’s deputy fire chief said, adding that the flames had been doused by firefighting teams.

“We heard a big sound, our windows shook,” one resident who did not give a name, told NDTV.

Police tried to clear crowds that gathered around the site of the incident.

The Red Fort, known in India as the Lal Qila, is a 17th-century, Mughal-era fort located in the old city and visited by tourists through the year.
