Wildlife authorities say rangers shot dead a poacher in northwestern Zimbabwe and seized 28 elephant tusks from a bush hideout.

The National Parks and Wildlife Authority said in a statement Tuesday the poacher, aged about 50, died in an exchange of fire over the weekend in Binga near the border with Zambia.

Authorities said that another 22 tusks were found last week near the Zambezi river upstream from Victoria Falls. They said one member of a six-man group of poachers was seriously wounded and hospitalized after clashing with rangers. The others fled.

The Wildlife Authorities said weapons, ammunition and a Zambia-registered cell phone were recovered.

Illegal ivory sells for about $250 a kilogram (2.2 pounds.) All 50 tusks could fetch nearly $60,000.
