The United States has pulled its men's under-17 team out of the U17 World Cup in Qatar, eight days before the tournament starts.
U.S. Soccer told players in a letter on 11 November. It cited safety concerns in the Middle East.
The tournament runs from 19 November to 13 December. The US had been drawn in Group J with Montenegro, Chile and Algeria.
Its first match was due on 21 November against Montenegro. The pre-tournament camp has been cancelled as well.
The letter pointed to the State Department's Level 3 advisory for Qatar. "The well-being of our players and staff will always be our top priority," it said.
That advisory, updated last month, urges Americans to reconsider travel because of the risk of armed conflict.
It cites Houthi attacks on Saudi Arabia, including on civilian airports. A war in the region began in February with US and Israeli strikes on Iran.
FIFA had not announced a sanction or a replacement team when the news broke. Late withdrawals can bring financial penalties.
The squad, named on 6 November, had 18 players born in 2009 and three born in 2010.
The US had been set to play a sixth straight edition. It will now have to qualify again for the next one.
