Play was disrupted at the World Championship after a protester climbed on to a table and covered it in an orange powder, the BBC report.

There were gasps from the crowd as the man interrupted Monday's match between Robert Milkins and Joe Perry.

Another protester tried to glue herself to the table where Mark Allen and Fan Zhengyi were playing but was stopped by referee Olivier Marteel.

A man and a woman were later arrested by South Yorkshire Police, the BBC reports.

Milkins and Perry's game was abandoned and will resume on Tuesday, while Allen and Fan re-started after a 40-minute break.

The protesters both wore T-shirts apparently in support of the group of climate change activists Just Stop Oil, who subsequently posted online to claim responsibility for the disruption to the event.
