(Sky News) Security officials are increasing monitoring of high-priority Islamist extremist suspects in Britain following the death of the leader of Islamic State, according to Sky sources.
The move is precautionary amid warnings of the potential for reprisal attacks by supporters of the group after Abu Bakr al-Baghdadi killed himself in a US special forces raid in Syria.
British police and security agencies typically increase the monitoring of known, high-priority suspects in the wake of a terrorist atrocity or other significant moment that might prompt reprisal killings or copycat incidents, a Whitehall source said.
For example, this happened after a suspected right-wing extremist killed dozens of worshippers at two mosques in Christchurch, New Zealand, in March.
