UK terror threat level under close review after foiled alleged attack plot in Europe

Arrests in Germany and the Netherlands increase fears that Jewish institutions in the UK could be targeted by Hamas

Britain’s terror threat level is being kept under “very close” review amid concerns that extremist groups could target Jewish institutions in the UK, a day after German prosecutors said they had foiled a Hamas attack plot by making four arrests.

MI5 and counter-terror police indicated they were focused on whether the war in the Middle East could galvanise extremists into taking violent action, as Israel’s intense bombing of Gaza extends to its third month.
