US President Donald Trump and Fifa president Gianni Infantino have close ties

Rights groups have urged fans, players, journalists, and other visitors to this summer's World Cup to "exercise caution" if travelling to the United States.

More than 120 organisations have collectively issued a 'travel advisory' driven by what they say is "the Trump administration's violent and abusive immigration crackdown".

"The Trump administration's rising authoritarianism and increasing violence pose serious risks to all," the message states.

It adds minority groups in particular are "vulnerable to serious harm", and is critical of Gianni Infantino, president of football's world governing body Fifa, for his close ties to US President Donald Trump.
