ISIS PLOT ON QUEEN

Drones take out terrorists who targeted royals

Britain launched a drone strike in Syria that killed three ISIS terrorists who had plotted to assassinate the queen and other members of the royal family with a huge bomb at the country’s VJ Day celebration in London, Prime Minister David Cameron revealed Monday.

“There was a terrorist directing murder on our streets and no other means to stop them,” Cameron said about the Aug. 21 drone attack — the first British military action in the Syrian civil war.

Two of the terrorists were Britons, he said, who had helped hatch the scheme to assassinate Elizabeth (inset), Prince Charles and likely hundreds of others at the Aug. 15 celebration marking the 70th anniversary of the end of World War II.

British intelligence agents thwarted the plot, which involved the detonation of a massive pressurecooker bomb, similar to those used by Islamic extremists at the 2013 Boston Marathon.

Cameron told Parliament that the precision strike on a car in the Syrian city of Raqqa, ISIS’s selfdeclared capital, came after “meticulous planning,” and that British nationals Reyaad Khan and Ruhul Amin were killed along with another, unidentified militant.

Cameron said the government reserved the right to take military action without Parliament’s approval when there is a “critical” British interest at stake or when a “humanitarian catastrophe” is imminent and can be averted.

“I am not prepared to stand here in the aftermath of a terrorist attack on our streets and have to explain to [Parliament] why I did not take the chance to prevent it when I could have done,” he said.

The terrorists were also believed to have plotted other attacks in Britain, including at the annual Armed Forces Day event in London over the summer.

Both plots were among six attempts to launch major terrorist operations in Britain that were stopped by security services, Cameron said.
