Counter-terrorism police are warning there could be an increased risk of attacks in the UK because of the Israel-Gaza conflict.
Reports to the anti-terror hotline between 7-25 October doubled compared to the same period last year.
The number of reports containing information classed as significant also rose by nearly four times.
UK police say the Israel-Gaza conflict could have an “energising effect” on those considering attacks.
On 7 October, Hamas launched a surprise attack on Israel, killing 1,400 people and taking more than 200 people hostage. Since then, Israel has been bombing Gaza, with more than 10,000 people killed, according to the Hamas-run health ministry.
Counter-terrorism police data shows the hotline received 1,350 reports between 7-25 October compared to 620 in the same period the year before.
