A ROCK concert in Rotterdam was cancelled at the last minute after cops foiled a potential terror attack last night.

US band Allah-Las called off their gig after armed cops swooped on a van reportedly loaded with gas canisters circling near the venue.

Rotterdam's mayor revealed Dutch authorities were tipped-off by Spanish police about the terror threat at 7pm - shortly before the doors were due to open to hundreds of music fans.

The band were seen being led from the 1,000-capacity concert hall by cops in bullet-proof vests before it was searched by anti-terror officers.

It is not clear if any fans were already inside the Rotterdam venue before it was evacuated.

The bomb squad was called in to search the Renault van with Spanish licence plates stopped just two streets from the Maassilo concert hall.

But Mayor Ahmed Aboutaleb said it was too soon to link the vehicle to the terror alert.

It comes less than a week after two terror attacks in Spain that left 15 people dead after a failed bid to build bombs using gas canisters.

Dutch police said the arrest of the Spanish driver is not directly connected to the recent atrocities in Barcelona and Cambrils in Catalonia.

The Californian band said in a statement: "Due to a potential terror threat at The Maassilo in Rotterdam, the Allah-Las show was cancelled tonight.

"Details are not available at this time as the incident is still under investigation.

"The band is unharmed and are very grateful to the Rotterdam Police and other responsible agencies for detecting the potential threat before anyone was hurt."

"Sorry for the inconvenience, more information follows."

A large area around the venue was cordoned off while the bomb squad was called in to investigate the van.

Pictures show several officers using torches to inspect the suspicious vehicle.

witness Usama Mohamed told AFP: "What I saw was a vehicle with lots of gas cylinders inside and inside the boot."

Los Angeles-based Allah-Las, who are on a tour of Europe, have caused offence in the past.

The band chose to use Allah - Arabic for god - because they wanted something "holy sounding".

But last year they revealed they had received complaints over the religious reference.

They once had a concert in Turkey cancelled because the promoter didn't feel comfortable with their name.

Lead singer Miles Michaud told The Guardian: “We get emails from Muslims, here in the US and around the world, saying they’re offended, but that absolutely wasn’t our intention.

“We email back and explain why we chose the name and mainly they understand.”

Holland has so far been spared from the horror of terror attacks which have rocked its closest European neighbours in past years.

But national counter-terrorism coordinator Dick Schoof warned in May 2016 that is at risk of a possible attack.

He said: "The threat level to the Netherlands is substantial which means that an attack in the Netherlands is a real danger and can actually happen."

Last week 15 people were killed in two depraved terror attacks just hours apart in Barcelona and Cambrils in Catalonia.

Thirteen people died and more than 130 injured in an horrific van and knife attacks on the Las Ramblas.

Horrifying footage showed bodies strewn across the famous street.

Another person died in a separate but linked attack in the nearby town of Cambrils where five suspects were killed by cops.
