RIYADH, Saudi Arabia — Lufthansa airlines said one of its cargo planes was involved in an accident while landing today in the Saudi Arabian capital of Riyadh. Saudi witnesses and an airport official said the plane caught fire and crashed while landing.

A Riyadh airport official said the plane caught fire as it was landing, crashed and split in two halves. He said the pilot and co-pilot were lightly injured and were rushed to a hospital. There was no further word on casualties.

A Deutsche Lufthansa AG spokeswoman at the airline headquarters in Frankfurt, Germany, said the plane did not crash but was involved in an accident. The spokeswoman, who declined to be named in line with company policy, said she could not yet provide further details.

The Arab satellite TV channel Al-Arabiya aired live footage from the airport showing the plane on fire and black smoke billowing into the sky.
