Seven people were killed on Monday as their car collided with a truck in Haryana’s Jhajjar district, leading to a massive pileup involving nearly 50 vehicles, police said.

The accident took place on the Rohtak-Rewari highway in the morning, resulting in a pileup as multiple vehicles rammed into each other due to reduced visibility caused by dense fog in the area.

Reports say that all the victims belong to the same family and six out of the seven killed are women.

School buses, cars and SUVs collided causing a 2 km-long traffic jam on the highway.

Images from the accident site showed wrecked vehicles being removed from the highway.
