A Tokyo woman was killed and a male traveling companion wounded by gunfire Thursday when their car was ambushed near Kafue National Park in southern Zambia.

The Tokyo travel agency that arranged the safari tour identified the deceased as Tsuneko Nogami, who was in her 60s, and the wounded man as Hirotsugu Iizuka, 66, also from Tokyo. The driver of the car, a Namibian national, was also wounded.

Hisahiro Kumazawa, president of the travel agency Dososhin, said in Tokyo that six Japanese -- five tourists and a tour guide -- were traveling in two four-wheel-drive vehicles when they were attacked on a main road about 35 km outside the national park.

The motive for the attack and the number of attackers involved were not immediately known.
