Pakistan arrests officers after shooting that left 4 dead Authorities in Pakistan have arrested counter-terrorism police officers after they killed a middle-aged couple and their 13-year-old daughter in what the police initially claimed was a shootout with insurgents

MULTAN, Pakistan -- Authorities in Pakistan have arrested more than a dozen counter-terrorism officers after police shot and killed a middle-aged couple, their 13-year-old daughter and another man in what they initially claimed was a shootout with insurgents, officials said Sunday.

The police killed grocery store owner Mohammad Khalil, his wife Nabila, their daughter Areeba and a family friend, Zeeshan Javed, after stopping their vehicle late Saturday. Police said Javed was a wanted terrorist and initially accused him of using the others as human shields.

Family members and witnesses say police killed the four in cold blood. They say police rear-ended the vehicle to stop it after a car chase. The police then removed three small children from the vehicle before opening fire, killing everyone inside, according to the witnesses. Video footage shot by a bystander and aired by Pakistani media appears to support the witnesses' accounts. No weapons were found at the scene.

The shooting sparked widespread outrage, with hundreds of mourners gathering in the eastern city of Lahore, where the victims of the shooting lived, and chanting against the police. Area residents left the bodies in the road as a form of protest following Saturday's shooting, which took place in the nearby town of Sahiwal.

Authorities say they have launched an investigation and arrested 16 officers involved in the shooting.

Prime Minister Imran Khan tweeted that he was "shocked at seeing the traumatized children who saw their parents shot before their eyes" and said "swift action will be taken." Usman Buzdar, the chief minister in the Punjab province, met with the family and promised that justice would be served.

Pakistan's security forces have been accused of extrajudicial killings in the past. In one of the most notorious incidents, a police officer was accused of killing a 27-year-old aspiring fashion model from a prominent Pashtun tribe last January, sparking widespread protests and allegations of police brutality. The officer was suspended and placed under house arrest pending trial.
