Congo ? A U.N.-run radio station says a passenger plane overshot a runway in eastern Congo and landed in lava, injuring 20 people.

Radio Okapi said the plane was flying from Kinshasa to Goma on Thursday and passengers had warned the crew that there were heavy clouds. One passenger told the station that the plane had landed in lava near Goma’s airport.

An official from the U.N. mission in Congo, who spoke on condition of anonymity because he does not have permission to speak with media, said there were 117 passengers aboard.
