The landslide submerged two vessels at the port of Iparia in the Amazon jungle region of Ucayali, according to a police report cited by the Andina news agency.

The number of people on board has not been confirmed, but the COEN national emergency operations center said there were about 50 passengers on one and none on the second.

Navy captain Jonathan Novoa told AFP by telephone that nine bodies had been recovered, while 25 people were reported injured and possibly "40 missing."

Authorities were working with families gathered at the scene of the disaster to try to determine exactly how many people still need to be located.

Images broadcast by the UTV Noticias channel showed distraught people running up and down the river bank as luggage and merchandise from the sunken boats floated in the river.

Without providing a toll, the COEN said on X that tragedy struck at dawn due to "erosion" of the bank of the Ucayali river.

It said the navy had been called in to help.

Novoa said the rescue effort was complicated by fast-flowing water and whirlpools in the river.

"We are in the flood season... and at the time of the accident there was fog, and the tasks are complicated," he said.
