KATMANDU, Nepal — Indian troops opened fire on hundreds of Bhutanese refugees who have been trying for two days to cross the small patch of Indian territory that separates Nepal from their homeland, officials said.

At least nine people were shot and wounded, said Narhari Adhikari, a police official on the Nepalese side of the border. An Indian official said troops fired about 30 rounds after the refugees hurled stones at border guards.
