A landslide in northern India caused boulders to tumble down a mountain and strike a vehicle, killing at least nine people, many believed to be tourists, and destroying a bridge.

       Dramatic video showed the boulders rolling into a valley in the Himalayan state of Himachal Pradesh. The Reuters news agency cited the Indo-Tibetan Border Police as saying that the vehicle had been carrying 11 people. In addition to the nine killed, two others, as well as a passer-by, were injured, Reuters said, citing its partner news agency ANI.India’s prime minister, Narendra Modi, offered his sympathies to relatives of those killed.

       “My heartfelt condolences to the families of those who lost their lives in this,” Mr. Modi wrote on Twitter, according to Reuters. “All arrangements are being made for the treatment of those injured in the accident.”

       Reuters quoted local news media as reporting that the people in the vehicle who were killed were visiting from India’s capital, Delhi, and elsewhere in the country.
