Congo's Health Ministry says at least 39 people are dead and more than 80 people have been hospitalised after a tanker truck collided with another truck in western Congo.
The ministry gave the official updated toll Sunday for Saturday's accident in the village of Mbuba, not far from Kisantu city and about 200km southwest of the capital, Kinshasa.
Witnesses say villagers rushed to collect leaking fuel from the vehicles when a fire broke out. The fire quickly spread to nearby homes.
The ministry said 20 people died immediately and of more than 100 transferred to a hospital, 19 later died. The toll is provisional.
President Joseph Kabila had on Saturday ordered three days of national mourning.
