While King of Saudi Arabia Abdullah warns that terrorists will attack on European countries during the next month if authorities do not proceed to preventive actions, UK raises the terror threat from substantial to severe and is one step before seizing the passports of British citizens who are prepared to fight on the side of jihadists in Syria and Iraq.

David Cameron has estimated that about 500 people have traveled from UK to Syria and perhaps to Iraq to fight. The British Prime Minister has stated that Islamic State is the “greatest and deepest terror threat” that Britain has faced up to now.

At the same time, the British authorities fear that jihadists are planning attacks during their return to UK.

The new anti-terrorism measures are expected to be presented today in the House of Commons.

However, according to BBC which claims a government source, British nationals suspected of being involved in terrorist activities should be allowed to hold their citizenship but they will not be allowed to enter the country for some time. According to the government source, this proposal is one of many that were under consideration and that “the details of the package completed” will be announced today by the Prime Minister.

The level of threat from international terrorism to Britain has been raised from substantial to severe and was announced by Theresa May, the home secretary, last Friday. This action is “related to developments in Syria and Iraq, where terrorist groups are planning attacks against the west”.

This means that an attack is “highly likely”, though May said that there is no evidence to suggest an attack is imminent.
