Reports to a UK police counter-terrorism hotline have more than doubled since the Hamas attack on Israel.

Police said that between October 7 and 25 the anti-terror hotline received around 1,350 reports, more than twice the number of contacts compared to the same period last year.

The number of reports with information useful to investigators went up by nearly four times to 200.

Deputy Assistant Commissioner Laurence Taylor said: “Sadly, history tells us that events overseas can inspire or accelerate acts of violence much closer to home. We are working day and night with our partners to monitor the threat picture.

“We’re acutely aware of the energising effect the conflict could have on those with extremist or terrorist intent.

“With that in mind, our Counter Terrorism Units across the country are reviewing their casework and checking that operational police activity is as effective as it can be to keep people safe.

“Critical to this work is the support of the public. As the increase in the number of reports to Counter Terrorism Policing in the last month shows, there is a real willingness from our communities to tell us about their concerns.

“To those who have contacted police, thank you, your information can have a huge impact on what we do.”

The national counter-terrorism squad that monitors material online has also seen a rise in referrals, with nearly 2,000 made by the public since October 7.

Of these more than 350 have been found to require further investigation to see if the content breaks terrorism laws.

Police are urging members of the public and businesses to remain alert to the risk of possible terrorist activity over Christmas and the New Year.

Mr Taylor added: “The coming months are filled with brilliant events and activities, where people will be coming together to enjoy the festive season.

“Sadly, we have seen before that terrorists can view these as attractive targets.

“Whilst we are working incredibly hard, with our partners, to make sure you can enjoy this time of year safely – our message is simple, stay alert and trust your instincts.

“Whether you’re a business, an event organiser, a local authority or simply heading out with family and friends, if you see something that doesn’t feel right, please report it.

“You won’t be wasting our time and you could save lives.”

Reports of suspicious activity related to terrorism can be made online at gov.uk/ACT or by calling 0800 789 321.

Terrorists are hunting for fresh targets because there are fewer crowds amid the coronavirus pandemic, the new boss of MI5 has warned.

Director general Ken McCallum said the security service has been “rapidly adapting” how it works to keep the country safe during the outbreak as well as helping research efforts in combatting the virus and trying to protect work on the vaccine from potential interference.

Speaking to reporters on Wednesday for the first time since taking on the top role in April, he said: “I stepped into this role at the height of the Covid lockdown, and for MI5 just like everyone else, 2020 has been dominated by the pandemic.

“We’ve sought where we can to help on Covid itself – advising on the safe construction of Nightingale hospitals; repurposing research originally done on toxic chemicals to help understand how Covid in droplets might disperse in certain environments; offering our skills in data analytics and modelling; simply allowing medically-qualified MI5 officers to step away from their duties here and directly support our NHS.

“And, crucially, on the vaccine, we’ve been working to protect the integrity of UK research.

“Our larger task has been rapidly adapting how we perform our core role of keeping the UK safe.

“The big shifts in everyone’s lives – reduced travel, more online, and the rest – mean shifts in how our adversaries are operating.

“Fewer crowds mean terrorists look at different targets; online living means more opportunities for cyber hackers; and so on.

“Equally, 2020 has demanded shifts in how MI5 itself has to operate; you wouldn’t expect me to get into detail, but common sense will tell you that covert surveillance is not straightforward on near-empty streets.”

Mr McCallum, who is in his forties, became the youngest ever director general when he took over from Sir Andrew Parker, who retired after leading the organisation since 2013.

The maths degree graduate, who grew up in Glasgow, has been the deputy director general since April 2017 and has 25 years of experience at MI5 including work on Northern Ireland-related terrorism, Islamist extremism and cyber security.

His career has seen him take charge of the service’s response to the attempted assassination of former spy Sergei Skripal in the Salisbury nerve agent attack as well as leading the response to the 2017 terror attacks and taking charge of counter terrorism investigations and risk management surrounding the 2012 London Olympics.

Wildfires tore across central and northern Israel on Thursday, forcing tens of thousands of residents to flee the city of Haifa, as leaders blamed arsonists for some of the blazes and branded them terrorists.

Television pictures showed a wall of flames raging through central neighbourhoods of Israel’s third largest city. Firefighters dowsed a petrol station with water as the blaze edged closer.

The fires have been burning in multiple locations for the past three days but intensified on Thursday, fuelled by unseasonably dry weather and strong easterly winds.

“Every fire that was caused by arson, or incitement to arson, is terrorism by all accounts. And we will treat it as such,” Prime Minister Benjamin Netanyahu told reporters gathered in Haifa. “Whoever tries to burn parts of Israel will be punished for it severely.”

Internal Security Minister Gilad Erdan referred to “arson terrorism” and said there had been a small number of arrests, providing no other details.

On social media, some Arabs and Palestinians celebrated the fires and the hashtag #Israelisburning was trending on Twitter.

“It’s likely that where it was arson, it goes in the direction of nationalistic,” Police Chief Roni Alsheich told reporters, without going into further detail.

With fires burning in the forests west of Jerusalem, around Haifa, on central and northern hilltops and in parts of the Israeli-occupied West Bank, the government sought assistance from neighbouring countries to tackle the conflagration.

Greece, Cyprus, Croatia, Turkey and Russia offered help, with several aircraft already joining efforts to quell the blaze, dropping fire-retardant material to try to douse the heaviest fires and stem their spread.

Netanyahu said he had asked for a “Super Tanker” fire fighting aircraft to be sent from the United States.

The Palestinian Authority had offered assistance as well, he said.

A thick haze of smoke hung over Haifa, which rises up from the Mediterranean Sea overlooking a large port. Schools and universities were evacuated, and two nearby prisons transferred inmates to other jails, a prisons service spokesman said. Patients were moved out of a geriatric hospital.

WORRYING FORECAST

A lack of rain combined with very dry air and strong easterly winds have spread the fires this week across the centre and north of the country, as well as parts of the West Bank. Hundreds of homes have been damaged or destroyed but no deaths or serious injuries have been reported.

Education Minister Naftali Bennett, the leader of the Jewish Home party which supports settlements in the West Bank where Palestinians seek statehood, said on Twitter that arsonists were disloyal to Israel, hinting that those who set the fires could not be Jewish.

“Only those to whom the country does not belong are capable of burning it,” he said in a tweet in Hebrew.

Haifa’s mayor said he feared for the city and called on residents with water sprinklers to turn them on to help keep the flames at bay. Those leaving their homes were urged to go to sports stadiums and other safer locations.

Highway 443, which links Jerusalem and Tel Aviv as it cuts through a southern flank of the West Bank, was temporarily closed to morning rush-hour traffic as flames reached the city of Modi’in, about half way between the two conurbations.

Local weather forecasters have said the tinder-dry conditions – it has not rained in parts of Israel for months – and strong winds are set to continue for several days and they see little prospect of normal seasonal precipitation arriving.

“Meteorology is not responsible but it is conducive to the spread of these fires,” said Noah Wolfson, the chief executive of weather forecasting company Meteo-Tech. “The atmosphere will remain very dry, at least until Monday or Tuesday.”
