The British Defence Secretary Michael Fallon said that “The cities of London, Manchester and Glasgow can easily be subject to attacks like those that took place in Paris” in which 130 people were killed in simultaneous attacks carried out with weapons and suicide bombs targeting music concert-goers, a football stadium, restaurants and bars.

He added that “there is always a danger in war, but the biggest danger is not doing anything against ISIS and leaving our streets vulnerable to a massacre like the one we saw in Paris”. Fallon told the BBC that it is “dangerous not to try to eliminate ISIS by using force”. Britain has not participated in bombing ISIS in Syria until now, after members of parliament voted against a resolution to launch air strikes on Syrian Army targets in 2013.

Scotland Yard arrested the radical leader Anjem Choudary on Saturday for violation of bail conditions after he met an extremist who is accused of supporting ISIS. Choudary is also accused of terrorism and has an electronic tag attached to his right leg.

Choudary is scheduled to appear before the Old Bailey in an urgent trial on the 11th of December with Mohammed Rahman who is a co-defendant in the same case and is suspected of being a member of a banned terrorist organisation according to Asharq Al-Awsat who obtained this information from sources at Scotland Yard.

Scotland Yard has accused Choudary, the leader of the Al-Muhajiroun movement, of providing ISIS with support from the 29th of June 2014 until his arrest in March 2015 during police raids on 18 buildings in London. Other raids were also carried out in Stoke-on-Trent, central England.

The British Defence Secretary Michael Fallon said that a parliamentary vote regarding military action against ISIS in Syria is uncertain at a time when the government is striving to achieve consensus on the subject. Fallon said that he hopes that ministers of parliament from all parties will consider the arguments, with the Labour Party extremely split on the issue.
