Six Burundi teenagers competing at the First Global International Robot Olympics in Washington, DC, were reported missing on Wednesday after disappearing from the event on Tuesday.
The Metropolitan Police Department in DC confirmed in an email that Don Ingabire, age 16, and Audrey Mwamikazi, age 17, "were last seen leaving the US into Canada" and that there is nothing yet that suggests foul play. The other four teens are reportedly still in the United States.
A Metropolitan Police representative said the investigation is ongoing.
The robotics competition attracted headlines earlier this month when Afghanistan's team of six girls was denied visas twice. President Donald Trump later intervened to find a way to permit the girls entry, according to reports.
