Four Islamic terrorists planned to kill the Queen of England this weekend — but British police foiled the assassination plot, reports said.

The anarchist assassins intended to stab Queen Elizabeth II Friday as the country celebrated 96 years since the end of World War I — an annual British jubilee — with numerous public appearances by her Royal Highness.

British police discovered the murder plot by the four terrorists, ranging in age from 19 to 27, and conducted multiple raids in West London and Buckinghamshire to thwart their plan.

Cops believe the suspected terrorists planned to use a knife to kill the beloved 88-year-old Queen, but also think they likely had access to firearms.

Officials made Queen Elizabeth and Prime Minister David Cameron aware of the potential threat, but her Royal Highness still plans to attend the weekend’s festivities.

She was expected at Saturday’s annual Royal British Legion Festival, a military bash that celebrates the end of World War I, The Sun first reported.

Her Majesty is still slated to lay the first wreath at Sunday Remembrance celebration following a two-minute moment of silence, according to The Sun.

This is not the first time the Queen’s life has been threatened.

The Lithgow Plot was an assassination attempt on the Queen and her husband, Philip, who were on a royal tour in Australia.

The lovebirds were traveling from Sydney to Orange in 1970 when their train struck a large wooden log, that was allegedly placed on the tracks in hopes of causing the train to derail as it came barreling full speed down the track.

But, for some reason, the train was traveling at an unusually slow speed, averting any crisis and sparring their lives.

The royal couple was reportedly kept in the dark about the 1970s murder plot to avoid embarrassment for the Australian government, The Daily Mail reported.

She has reigned Queen for more than five decades, assuming the title at age 25. Prince Charles, her oldest son, is next in line to the throne, but is expected to pass the honor to his son, William.

The Duke of Cambridge and his wife, Kate Middleton, welcomed a son to the royal family last July and are expecting another child in April.
