ISLAMABAD, May 8 (CGTN) -- At least five people, including three policemen, were killed and 24 others injured on Wednesday morning in a blast near a police vehicle outside a shrine in Pakistan's eastern city of Lahore, a police official said.

According to the reports, the blast hit the police vehicle, which was present for the Data Darbar, a famous shrine in the provincial capital of the eastern Punjab province.

Police and rescue teams rushed to the site, transporting bodies and the injured to the city's Mayo Hospital.

Hospital officials feared that the death toll might rise as several of the injured are in critical condition.
