UK raises terror threat level in Northern Ireland ahead of Biden visit March 28, 2023 at 03:58AM

The UK government raised the terrorism threat level in Northern Ireland to "severe" on Tuesday, ahead of an expected visit by US President Joe Biden to mark the 25th anniversary of a landmark peace accord. The domestic spy agency MI5 judged that the risk of an attack had gone from "substantial" to "severe", meaning an incident is judged "highly likely", Northern Ireland Secretary Chris Heaton-Harris said.
