Considering the way things have transpired in the ongoing World Cup, tournament chiefs are trying their best to establish a no-fly zone over Lord's for the summit clash on July 14.

The decision has been taken after political banners were flown in Birmingham during Thursday's semi-final between England and Australia. The signs read "World must speak up for Balochistan" and "Help end disappearances in Pakistan".

"We do not condone any sort of political messages at the ICC Men's Cricket World Cup," the ICC said in a statement.

"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 (Sunday's) final at Lord's."

The sky above Old Trafford stadium was declared a “No Fly Zone” during the first semi-final between India and New Zealand after a private plane displayed anti-India banners during the team’s last group fixture against Sri Lanka at Headingley on July 6. The aircraft flew over the ground had displayed messages like “India stop genocide and free Kashmir” and “Justice for Kashmir”.

It was the second such breach of security after another aircraft flew with the banner “Justice For Balochistan” during the game between Afghanistan and Pakistan on June 29. A number of fans were evicted after a fight inside the stadium, which is believed to have been triggered by the banner’s display.
