Chile to investigate reported UFO sightings

The Chilean airforce has set up a special committee to investigate reported sightings of unidentified flying objects, or UFOs.

A government spokesman said reputable sources -- such as pilots and air traffic controllers -- had sometimes reported seeing objects for which there was no immediate explanation.

The committee, he said, would attempt to determine whether or not the objects were naturally-occurring phenomena.

There are said to have been about sixty incidents this year alone.

In May a convention of UFO experts was held in the Chilean capital, Santiago.
