Thirty-five foreign nationals have been killed and four others injured in a bus crash near the Muslim holy city of Medina in western Saudi Arabia.

The bus collided with a “heavy vehicle” in al-Akhal Centre at 19:00 (16:00 GMT) on Wednesday, state media said.

The passengers were expatriate Arabs and Asians reportedly travelling from Medina to Mecca for a pilgrimage.

Their nationalities are not known, but Indian Prime Minister Narendra Modi said he was “anguished” by the news.
