The Football Association has condemned the behaviour of England fans who clashed with Portuguese police in Porto on Wednesday.
Bottles were thrown at Portuguese supporters watching their team beat Switzerland 3-1 in the first UEFA Nations League semi-final at a fan zone, as well as at police.
Per BBC Sport, a statement issued by the FA said:
"The FA strongly condemns the scenes witnessed in Porto overnight.
"Anyone responsible for these disturbances cannot be seen as true England supporters and are not welcome in football. They are an embarrassment to the team and the thousands of well-behaved fans who follow England in the right way.
