Witnesses say carriages were added to accommodate extra passengers. In this image made from video, people walk beside a derailed train carriage after an accident in Eseka, Cameroon, Friday, Oct. 21, 2016.

The packed Camrail train had been travelling from the capital Yaounde to the port city of Douala.

On Saturday, October 22, at least 73 people were killed and 600 injured when a train carrying more than twice its capacity went off track in Eseka, Yaounde, Cameroon.

There will be an investigation into the cause of the derailment, according to the Cameroon president.

Cameroonian President Paul Biya, who is overseas, wrote on his official Facebook page: "I instructed the government to provide full assistance to the survivors". The accident happened in Eseka, about 125 kilometers (75 miles) west of Yaounde, which doesn't have adequate facilities and is hard to access by road, because of landslides caused by heavy rains.

The Cameroon Red Cross reported that the scene of the crash was remote, and made more hard to attend on account of poor weather conditions.

The collapse of a section of the main highway between Yaounde and Douala amid heavy rain earlier on Friday had blocked hundreds of vehicles on the road and prompted increased numbers of passengers to make the journey by rail.

One of those injured died as he arrived in Douala, and "we are doing everything possible to save the lives of the close to 200 victims sent to Douala", said Governor Ivaha Diboua Dieudonne of the western Littoral region.
