The International Cricket Council reacted with anger on Thursday night after a light aircraft breached a no-fly zone in Birmingham
to display a political message during England's World Cup win over Australia.
The plane - trailing a banner which read 'World must speak up for Balochistan' - circled Edgbaston four times during Australia's innings before being ordered out of the area by air authorities.
'We do not condone any sort of political messages at the World Cup,' said an ICC spokesman.
'We have worked with local police forces around the country throughout the tournament to prevent the World Cup being used as a platform for political protests, so we are incredibly disappointed these flights continue to take place.
'We are working very closely with the relevant agencies to make sure there is an air exclusion zone in place for manned and unmanned flights during the final at Lord's.'
The incident followed the flying of provocatively-worded slogans on consecutive Saturdays at Headingley.
The first occurrence appeared to increase tensions between Pakistan and Afghanistan fans while seven days later 'Justice for Kashmir,' and 'India stop genocide,' were visible messages during the India v Sri Lanka match.
