At least 11 people died and six others were injured after two boats collided on the Huallaga River in the Peruvian district of Yurimaguas, authorities said Sunday. 

The accident took place at 4:20 a.m. local time on Sunday when a barge, which had sailed with around 80 people onboard from Santa Maria to Yurimaguas, was hit by a motorboat amid dense mist at dawn.

Peru's navy said at least 60 people have been rescued and nine remain missing. 

Local police have started an investigation into the accident.
