According to a report in the Sunday Times, Israeli officials have warned that an Iranian terrorist squad in Europe may be planning to attack its athletes at the 2012 London Olympic Games.

According to a report, more than 17,000 troops and 7,000 private security guards will secure the Olympic Park and 26 other venues, and an additional 12,500 police will be deployed to patrol London’s streets in a ”series of ‘rings of steel.’”

MI5 and New Scotland Yard are reportedly thought to have raised their threat assessment in light of the terrorist attack in Bulgaria on Wednesday that killed five Israelis and the Bulgarian bus driver. In addition, the Sunday Times reports, the Israeli government has dispatched agents from its domestic and foreign intelligence services to protect its 38-strong delegation.

Meanwhile, according to the report, Israel’s foreign intelligence service, the Mossad, is said to have sent a team, codenamed Bayonet, to Europe in search of a group of terror suspects believed to be working with Iran’s Quds force and Hezbollah. According to the Sunday Times, “Security experts say the Quds force — a unit of the Iranian Revolutionary Guards — has recruited a number of white European Islamic converts, including two Germans, one from Sweden and a couple of Britons.”

According to restricted New York police documents obtained by Reuters, Iranian Revolutionary Guards or their proxies have been involved so far this year in nine plots against Israeli or Jewish targets around the world. The reports detail two plots in Bangkok and one each in New Delhi, Tbilisi, Baku, Mombasa and Cyprus. Each plot was attributed to Iran or its Lebanese Hezbollah militant allies, said the reports, which were produced following the bombing in Burgas, Bulgaria of a bus carrying Israeli tourists.

In related news, a plaque has been unveiled near the Olympic village to honour the victims of the 1972 Munich massacre. London Mayor Boris Johnson was joined by Yossef Romano, nephew of one of the murdered Israelis, as wreaths were laid during the commemoration in an art gallery near Hackney Town Hall, organised by Councillor Linda Kelly and Martin Sugarman.
