In a new television ad -- his campaign’s first -- Republican presidential candidate Donald Trump shows footage of dozens of people swarming over a border fence. But the footage isn’t as it seems.

About halfway through the ad, a narrator says of Trump, "He'll stop illegal immigration by building a wall on our southern border that Mexico will pay for." Video footage shows dozens of people streaming across the border, as if they were ants fleeing an anthill.

The clear suggestion is that the footage is of the "southern border" between the United States and Mexico. But it’s not -- it’s 5,000 miles away, in a small Spanish enclave on the mainland of Morocco.

PolitiFact was able to trace the footage back to the Italian television network RepubblicaTV. On May 3, 2014, the network posted footage of Moroccans crossing the border into Melilla, one of two enclaves on the Moroccan coast that are held by Spain. Migrants who cross the border there are essentially entering territory held by a European Union nation, even though they are still on the African continent.
