Hundreds of people have seen "mystery drones" in the USA. People are worried because the drones are flying over army bases. A drone was also seen near a Donald Trump golf course. A New York airfield closed for an hour last week because of "suspicious" drone activity. The government said the drones were not a danger to people.

There are many drone conspiracy theories on social media. Some people are saying Russia and China are spying on the USA. A US politician said the drones were from Iran. The US said it would tell the American people if this was true. The FBI said most of the drone sightings were people making mistakes with what they saw.
