Elephants have killed five people in two separate attacks in eastern India. One of the animals died after being tranquilized.

Senior forest official Ajay Das said one man was killed Monday morning after he walked out of his home in a village in the Burdwan district of West Bengal state. The man encountered five elephants, and he was tossed in the air and trampled by one of them.

In a separate encounter Sunday in another part of the district, four people were killed when three elephants attacked them.

Das said one elephant in that group was tranquilized and later died. An adult female and a calf ran away.

As rapid urbanization cuts into India's forests, animals and humans have come into increasing conflict.
