LONDON (TheBlaze/AP) — Police in London have arrested four suspected Islamic terrorists in several raids throughout the British capital, and U.K. Telegraph defense editor Con Coughlin told Fox News that a plot to behead Londoners may have been foiled.
"This is a breaking story here in London, but the material that we have from Scotland Yard and the intelligence services is they have uncovered the first ISIS plot here in the U.K.," Coughlin said on Fox News. "Basically, British jihadists coming back to London and wanting to carry out a plot, and I'm told the plot was to behead people on the streets of London."
Police said Tuesday the four suspects are aged 20 and 21, and they were arrested on suspicion of preparing or instigating acts of terrorism.
"What I'm told about this plot is this group did recently come back from Syria, was planning to carry out beheadings -- I say plural -- on the streets of London in the next few days or so," Coughlin remarked, adding that the situation is still fluid and the information may change.
The suspects remain in custody, and homes and vehicles in west and central London are being searched as part of what police called an ongoing investigation into Islamic-related terrorism.
The terror threat in the U.K. was recently raised to "severe" because of the increase in the number of Britons traveling to Syria to join up with the Islamic State group. The government has said the militant group plans to strike targets inside Britain.
