An unnamed official told CNN that the authorities believe Daesh will try to attack Britain but details remain unclear. The official says concerns have been heightened following the decision by the British government to carry out airstrikes over Syria.

The details of an attack on British soil, according to a report by CNN, may have arisen from information extracted from a Daesh militant called Aine Lesley Davies, who has links to so-called Jihadi John. Davies was detained in Istanbul following intelligence gathered by British and Turkish authorities.
Elsewhere in Thailand, police have been warned by Moscow that ten Syrian members of Daesh have entered the south-east Asian country with the intention of targeting Russian tourists.

The leaked memo, marked "urgent" is dated from 27 November and was sent by a commander from Thailand's special branch to all police units.
It says Russia's Federal Security Service (FSB) had told authorities in Thailand that Daesh militants from Syria had entered the country between 15 and 31 October with the intention of targeting Russians.
"They traveled separately. Four went to Pattaya, two to Phuket, two to Bangkok and the other two to an unknown location."
Russia has been carrying out a separate aerial campaign against Daesh in Syria since September, at the request of Syrian President Bashar Assad and following the terrorist attack on an aircraft carrying Russian holidaymakers from the Egyptian resort of Sharm-el-Sheikh. All 244 people on board were killed.
The memo in Thailand calls for increased security around potential targets.
Meanwhile, Britain's security service MI5 says the global terror threat presents "a threat on a scale not previously encountered."
More than 2,000 firearms officers from London's Metropolitan Police Service (MPS) recently staged an operational terrorist attack in the capital. Firearms trainers posed as extremists, armed with automatic weapons and bombs, simulating an attack on a shopping center.
The MPS insists the exercise was part of an annual training program arranged months ago — but it was held on the morning of the Commons debate on whether to commence airstrikes in Syria.
MPs voted in favor of launching airstrikes by 397 to 223. They were launched just hours after the vote.
