UK MI5 chief warns of 'terror threat' amid Israel war on Gaza

Britain's domestic MI5 spy agency chief has warned that Israel's current war in Gaza increases UK terror risk, singling out Iran as a cause for concern.

The comments by MI5 director general Ken McCallum, reported in UK media Wednesday, following attacks by suspected Islamists in France and Belgium since violence erupted in the besieged Gaza Strip on 7 October, which has killed over 3,400 Palestinians, including at least 1,000 children amid relentless Israeli bombing.

"There clearly is the possibility that profound events in the Middle East will either generate more volume of UK threat and/or change its shape in terms of what is being targeted, in terms of how people are taking inspiration," McCallum said.

He was speaking to British media at a summit in the United States attended by its intelligence chiefs and counterparts from Canada, Australia and New Zealand.

"In the current climate, we and our partners are particularly attuned to the risk that terrorist organisations may choose to strike in a new way, or perhaps that individuals choose to respond often in spontaneous or unpredictable ways," he added.

McCallum, an MI5 veteran appointed to the top job in March 2020, rarely speaks in public.

In remarks specifically about Iran, he noted London had "been concerned" about its behaviour within Britain "for a long time", with the current crisis in Gaza heightening those concerns.

"In particular, the last 18 months or so have been a particularly intensive phase of Iran-generated threat on UK soil," he said.

The domestic spy chief added that Tehran had mainly targeted its "internal enemies, dissidents, Farsi media organisations" in the UK.

"Clearly one of the things on our minds is might the Iranian targeting intent shift in response to events elsewhere," he told the Daily Telegraph.

"I wouldn't rule out the possibility that could include the UK."

Assessing beyond the Middle East, McCallum noted the world had entered a new, more dangerous era, in which "authoritarian states" were "behaving much more aggressively".

"We are in a different world now than the world we've all lived in since the end of the Cold War," he said.

McCallum has previously used speeches to warn against the increasing espionage threat posed by China.

Speaking to the BBC at this week's security summit, he noted more than 20,000 people in Britain have now been approached covertly online by Chinese spies while warning Beijing is trying to steal cutting-edge research from Western nations.

"We have seen a sustained campaign on a pretty epic scale," Mr McCallum said.
