More than 118 people were injured in the explosion in the eastern province of Punjab,which came as people gathered to collect leaking fuel after the tanker overturned on Sunday, government officials and rescue workers said.
The disaster was one of several deadly events to mar the run-up to Monday's Eid al-Fitr holiday marking the end of the Muslim fasting month of Ramadan. At least 65 people were killed in bombings in two cities on Friday claimed by Islamist militants including the Pakistani Taliban and Lashkar-e-Jhangvi.
