Two ultralight aircraft collided near an aerodrome in northeastern Spain on Sunday, killing four passengers, regional authorities said.

Firefighters found one plane on fire in a wooded area near the Moia aerodrome north of Barcelona after being alerted by a witness who saw it lose altitude and crash, the regional government of Catalonia said.

Several hours later firefighters found a second damaged plane with two dead people inside about 300 metres (984 feet) from the first.
