A boat carrying students returning from state examinations sinks in central Democratic Republic of Congo, killing at least 20 people, according to authorities and multiple reports. ABC News and the Winnipeg Free Press both cite officials saying the incident involves a wooden boat transporting students back from exams. Al Jazeera reports that witnesses describe the boat as possibly carrying more than 200 passengers, though the confirmed number of people aboard is not settled in the available accounts. The reports describe drownings and do not provide details on the exact cause of the sinking, the time of day, or whether any passengers survive. Information about injuries, the location on the river, and ongoing rescue or recovery efforts is limited across the sources. Authorities are investigating the incident as they work to determine the number of people on board and to recover bodies. The case highlights safety risks for passenger transport on rivers in the region, where overcrowding and the condition of boats are recurring concerns.
