One of the illegal immigrants who escaped from the Safi detention centre on Tuesday is back at the centre after he was caught by soldiers, an army spokesman said.
The search for other escapees - it is not clear whether two or three escaped - is still on.
The escape led to the temporary closure of the main airport runway on Tuesday as the search for the immigrants was underway.
The control tower had informed the captains of three incoming to use the old runway because of the escape.
