A trucker sustained burn injuries when miscreants hurled petrol bomb at his parked vehicle in Daudkandi upazila of Comilla early yesterday.

The arson attack was carried out around 3:00am, barely three hours before the beginning of Jamaat-e-Islami-sponsored daylong hartal.

Reaz Uddin, 39, suffered 14 percent burns. He is undergoing treatment at the burn unit of Dhaka Medical College Hospital (DMCH).

The trucker was heading towards Chittagong after loading maize in Rangpur. He stopped the vehicle on the Dhaka-Chittagong highway in Pennai area to take a short break around 3:00am, said helper Munna.

They took tea in a nearby shop, he said, adding that he was on the truck's roof at the time of the attack.

"As he [Reaz] was taking a nap, three youths hurled a petrol bomb inside the truck through the window, setting the vehicle afire," he said. Munna also suffered minor injuries while jumping off the roof.

Hearing screams, locals rescued the driver and took him to a nearby upazila health complex. He was shifted to the DMCH as his condition deteriorated.

Stray incidents of violence also marked the yesterday's countrywide hartal. Jamaat called the hartal protesting the execution of its assistant secretary general Muhammad Kamaruzzaman for his 1971 ‪war crimes.
