Swiss champions FC Basel are to face disciplinary action after environmental activists briefly interrupted their Champions League match on Tuesday with a protest aimed at Russian-owned Gazprom, one of the competition sponsors.
.
Uefa said Basel had been charged with "inadequate organisation" of the game at home to Schalke 04 after four Greenpeace protesters wearing orange boiler suits descended on ropes which they had dropped from the roof and unfurled a huge banner.
.
The banner read "Gazprom, don't foul the Arctic" and "Free the Arctic 30".
.
The protesters then hauled themselves back on to the roof while officials watched from the touchline and the match continued.
