Canadian police have received authority to jam mobile phone signals during key events including the Group of Eight (G8) summit next week and the Pope's visit next month.
The Royal Canadian Mounted Police said on Friday that they and the Department of National Defense had been authorised to jam radios and mobile phones to foil attacks by remote-control bombs.
The US president George Bush, prime minister Tony Blair and Russian president Vladimir Putin are among the world leaders the Canadians will have to protect as hosts of the G8 summit at the resort of Kananaskis, Alberta.
Other G8 members are Canada, France, Germany, Italy and Japan.
The jamming authorisation runs from 17 to 29 June for the G8 summit and also applies to the nearby city of Calgary, where the media and some of the overflow diplomats will be based during the 26 to 27 June meeting.
The authorisation will also apply from 16 to 31 July for the 23 to 28 July visit of the Pope to Canada.
But a spokesman said that although the Mounted Police had authority to jam all signals, it was unlikely that many people would be affected.
If a signal was picked up in an area where it shouldn't be, then it would be jammed, but otherwise it would be business as usual, he said.
