2 lights moving oddly in the night sky

I was 9 years old, some of my friends called me outside my house, in a town of the island of Puerto Rico. I step out and look up to see what they were looking. I saw 2 lights just bigger than a star, moving in odd way up in the sky. You could see the starts not moving behind them, and this 2 objects move in rapid changes of directions. This event took place for close to 10 minutes, until they move out of view at very rapid speed. I remember it like today. Next day a report came out in the local newspaper, and it was seen by hundres of people all around the area.
Witness indicates that date of sighting is approximate.  PD
