At least 15 people have been killed after debris from a massive landslide hit a bus in India’s northern state of Himachal Pradesh, local authorities have said, Aljazeera reported.

The bus was travelling on a hilly stretch near Bilaspur district when, late on Thursday, a landslide struck following days of torrential rains. At least 20 to 25 passengers were on the bus at the time. Nine men, four women and two children were among those killed, police said.

Three injured children were rescued and admitted to a local hospital for treatment, according to a statement from the office of Sukhvinder Singh Sukhu, the state’s highest elected official. Rescue operations continued on Wednesday in an attempt to find other missing passengers who are believed to be dead, police said, according to Aljazeera.
