Thirty-six people died and six others were injured in a bus accident in the northern Indian state of Uttarakhand’s Almora district on Monday (November 4), according to the Associated Press, CNN And CBS News.

The bus, built to carry 42 passengers but with about 60 people on board, left Garhwal in the Himalayas for the town of Ramnagar, about 120 miles south of Garhwal.

During the trip, the bus lost control, left a hilly road and fell into a river about 200 feet below the road, a senior state official, Deepak Rawat, told the AP. Almora district officials rushed to the scene and worked to rescue passengers from the overturned bus.

Several passengers were ejected from the vehicle or fled. Those who survived then alerted authorities of the accident.

According to CBS News, Uttarakhand Chief Minister Pushkar Singh Dhami said emergency teams were “working quickly to evacuate the injured and take them to the nearest health center for treatment. Instructions have also been given to airlift seriously injured passengers if necessary.”

Dhami confirmed that an investigation into the accident would be launched.

State official Vineet Pal said preliminary information indicated the bus was not properly maintained and had skidded before falling into the ravine. Pal also said two transportation officials were suspended for allowing the poorly conditioned bus to travel, according to the AP.

Dhami said the state government would compensate the grieving families with 400,000 Indian rupees ($4,750) and the injured would receive 100,000 rupees ($1,190). Indian Prime Minister Narendra Modi also offered additional compensation, saying the families of those killed will also receive 200,000 rupees ($2,378) and those injured will receive 50,000 rupees ($594), according to CBS News.

Modi also offered his condolences “to those who lost their loved ones in this unfortunate road accident.”

India experiences hundreds of thousands of road deaths each year, among the highest in the world, according to the AP.

Most recently, in July, 18 people died when a double-decker bus collided with a milk truck in the state of Uttar Pradesh, the AP reported. Two months earlier, 21 people died after a bus lost control and rolled into a deep ravine on a mountain highway in Indian-controlled Kashmir.
