UK and Europe are '˜not safe places' - Trump

The Republican presidential front-runner was speaking five days after the two Brussels airport blasts and Metro bomb which killed at least 35 people, including three of the attackers.

He said Europe had lots of “very, very severe” problems and added that he did not even think America was a safe place for Americans.

Mr Trump told ABC: “I don’t think Bruss - England or I don’t think that Europe is a safe place. No, I don’t. I think there are a lot of problems in Europe that are very, very severe.

“When you look at Brussels, when you look at the way they’ve handled things from law enforcement standpoints, when you look at Paris, when you look at so many other places, no, it’s not (safe)”.

The comments made by the billionaire businessman were given support American secretary of state John Kerry who told CBS’s Face The Nation that US citizens should “avoid a crowded place” if they were travelling to Europe, because “you have no control over who may be there”.

In December Mr Trump was mocked by Britons for his comments on “no-go” areas in London, when he claimed that some areas of the capital were “so radicalised that the police are afraid for their own lives”.

His announcement came as Belgian officials completed their initial investigation at Brussels International Airport and found the main building to be stable. Airport officials are now discussing plans to install temporary check-in desks, but said the process of identifying a suitable location was still being carried out in consultation with airlines and luggage handlers.

Shortly after the announcement, Belgian media also reported that prosecutors in Brussels charged a second man in connection with a foiled attack on Paris.

It is understood the first arrest was made in Boulogne-Billancourt, west of Paris, where police detained Reda Kriket, 34, for his suspected involvement in a militant plot that officials believe was “at an advanced stage”.

On Saturday, an Algerian national wanted by the Belgian intelligence services, Djamal Eddine Ouali, was detained in Salerno, Italy.

He is understood to have been arrested under the European arrest warrant, in connection with the forging of fake ID documents used by the terrorists behind the Paris and Brussels attacks.

Confirming his arrest on Twitter, Italian police uploaded an image of the suspect being detained by armed officers, adding that he had been arrested for “aiding and abetting illegal immigration linked to the Paris massacre”.

Meanwhile in Brussels, despite the cancellation of a planned memorial march through the centre of Brussels on Sunday, Belgian riot police were forced to use water cannons on a far-right protest group which disrupted the large remembrance gathering at the central Place de la Bourse.

As members of the public laid floral tributes to the victims of Tuesday’s attacks at a makeshift memorial, police clashed with the demonstration group, which was seen making Nazi salutes and confronting ethnic minority groups.

After riot police failed to force the group back from the vigil, water cannons were used to disperse individuals to cheers by members of the crowd that had come to pay their respects.

Adrian Liston, who was present at the vigil, told the BBC that the memorial had been disrupted by a “bunch of skinheads” who had turned up “in force”.

Belgian prosecutors on Monday said three people arrested in swoops across the country yesterday face charges for participating in terrorist group activities. A fourth person has been released without charge. Authorities did not say if they were linked to the Brussels suicide bombings.
