Terror in London: Italian cops arrest two Afghan men 'who were plotting attacks in Canary Wharf and at top hotels in the capital'

TWO Afghan men have been arrested on suspicion of plotting deadly terror attacks in London’s Canary Wharf and at various hotels in the capital.

Italian cops arrested the pair in the southern Italian city of Bari after allegedly finding incriminating evidence a mobile phone.

The suspicious information was only recovered when the pair were held by police who wanted to question them both, as well as a third Afghan and a Pakistani man, after they were spotted filming inside a Bari shopping mall.

The investigation began in December after four Afghans were spotted taking videos inside a shopping centre in Bari in southern Italy, and a police search of their phones uncovered other images of the city's airport and port, as well as sites in Rome, Paris and London.

"It was clear these were not tourist images. They appear to have been scouting sensitive sites," prosecutor Roberto Rossi said at a press conference in Bari.

The phones also contained images of Italian and Afghan military vehicles and weapons, as well as Taliban propaganda videos and "a series of chants traditionally sung in preparation for martyrdom", he said.

One of the defendants was also seen in a photograph posing with an MS16 semi automatic rifle, which Rossi said was "not an easy weapon to find on the market".

He also had links on his smartphone to websites "only accessible to those with connections to the international jihadist network".

The suspects had been taking expensive trips around Europe, which they had paid for in cash, Rossi said.

Investigators also uncovered details of trafficking prices and routes of migrants into Italy, but also through Hungary or Calais.

But they were unable to pull information from one of the phones recovered: a locked iPhone.

The two men arrested had each been awarded a humanitarian residence permit in Italy -- one in 2011 and one last week -- and the latter was still living at a reception centre for asylum seekers when he was detained.

Interior Minister Angelino Alfano hailed the "success of a high-level inquiry" and said the case showed no country was "zero risk".

Police said the investigation would continue, with Rossi suggesting it was "likely" the wanted men had returned to Afghanistan and Pakistan, but could also be in other European countries.
