Two young Dutchmen arrested in the US for trying to enter a military base part of Nevada known as Area 51, have been each fined $2,280 and ordered to stay away from the area for a year, website Nu.nl reported.

The men, Ties Granzier aged 20 and Govert Sweep aged 21, both run YouTube channels and there was a drone, camera and laptops with them in the car they were driving. They were arrested a week ago, three miles inside the security zone, after telling police they had seen the signs but wanted to look at the site anyway.

Area 51, around 120 miles north of Las Vegas, is home to a heavily guarded US military base. According to UFO conspiracy theorists, it is also home to the remains from a flying saucer that supposedly crashed in Roswell, New Mexico in 1947.
