Concert in the Netherlands cancelled over terrorism threat

A concert in Rotterdam has been cancelled after a tip-off about a potential terror threat from Spanish police.

The city's mayor, Ahmed Aboutaleb, said gas bottles were found in a small van with Spanish number plates found near the venue, where American rock group Allah-Las were due to perform.

Police detained the driver, reported to be Spanish by the El Pais newspaper, and the vehicle was examined by a bomb squad.

Aboutaleb said it was "still to be established that there was a link between the van and the threat".

The incident is not connected to the attacks in Barcelona and Cambrils last week, a source told the Reuters news agency.

A Spanish counter-terrorism investigation official said Spain's Civil Guard received "an alert indicating the possibility of an attack today in a concert that was going to take place in Rotterdam".

The decision to call off the show was made at around 7pm local time, shortly before doors opened at the Maasilo concert hall.

The incident comes as Spanish police continue their investigation into the twin terror attacks which took place in Spain on 17 August.

Fifteen people were killed and 120 others were wounded in the attacks which took place on Barcelona's Las Ramblas district and in the coastal town of Cambrils.
