Lahore

More than 50 others were injured in the explosion on the busy Ferozepur Road close to a vegetable market in the south of the city.

The Pakistani Taliban said it was behind the explosion.

Reports suggest it was a suicide bomber on a motorbike, and the target may have been police working in the area. Police officers are among the dead.

Windows were blown out in nearby buildings by the force of the blast.

Eyewitness Sher Dil, who works at an office near the site, said he heard a "deafening blast".

Four of the dead were soldiers. Twenty-two others were wounded, officials say.

A team carrying out Pakistan's first census in nearly 20 years was the target of the attack, police said.

It comes amid a series of bombings claimed by Islamist militants in recent weeks. The Pakistani Taliban said they carried out the attack.

The site of the blast near Bedian Road has been cordoned off.

It was not immediately clear if the two civilians killed were census workers or bystanders.

Security forces have been frequent targets for the militants.

More than 300 other people were wounded, officials said.

The explosion occurred in the parking area of Gulshan-e-Iqbal Park close to children's swings.

The park is a popular site for members of Lahore's Christian community, many of whom had gone there to celebrate the Easter weekend holiday.
