DHAKA, Bangladesh —  A news report says villagers and forest guards have beaten to death a protected Royal Bengal tiger after it killed three people near the world's largest mangrove forest in southwestern Bangladesh.

The United News of Bangladesh agency says the tiger strayed into Kadamtala village late Friday and killed three people.

The tiger also injured a fourth person and killed five goats in the area. Villagers and officials surrounded the tiger and waited until morning to kill it.

The Sundrabans mangrove forest, 110 miles southwest of the capital Dhaka, is a U.N.-declared world heritage site and home to Royal Bengal tigers.

Officials could not be reached for comment Saturday.
