13 dead, 80 injured and 2 suspects arrested in the wake of Barcelona terror attack.

At least 13 people have been killed and dozens injured in Barcelona after a van ploughed into pedestrians in a busy tourist street.

More than two hours after the atrocity a man was shot dead after driving through a roadblock in a Ford Focus and opening fire, injuring two police officers.

ISIS has claimed responsibility for the attack, describing the killers as 'soldiers of the Islamic state'. Terror police have arrested two suspects.

One of them is believed to be Driss Oukabir, a Catalan resident in his late 20s of Moroccan origin. It is unclear who the second detained suspect is, but unconfirmed reports in Spain have suggested Oukabir's brother has been taken into custody.

Oukabir, who has reportedly served time in a Spanish prison, had earlier rented one of the vans used in the deadly attack.

Horrifying pictures and video from the scene show armed police and paramedics rushing around Las Ramblas, a busy promenade in the centre of the city, as victims lie hurt in the street.

It remains unclear how many attackers were involved in the massacre, which is being treated by police as an act of terrorism.

The president of Spain's Catalonia region says police have arrested two people following the van attack, which happened in Barcelona's bustling Las Ramblas district.

In a brief news conference this evening Carles Puigdemont said 12 people are confirmed dead and at least 80 have been hospitalised after the van drove onto a sidewalk and swerved through a busy pedestrian area.

The region's interior minister had earlier tweeted that 13 people had died in the attack.

Barcelona Mayor Ada Colau says a moment of silence will be held in the city's main square at noon Friday 'to show that we are not scared and we are more united that ever'.

Police have confirmed that at least 84 people are hurt, with Catalonia's interior minister Joaquim Forn saying it is 'very possible' that the number of dead will rise because of the 'very serious' wounds to victims. 

The civil guard has said the van used in the attack was rented by Oukabir in the town of Santa Perpetua de la Mogada, which is around 15 miles by road from the scene of today's killings.

A second van was found parked in the town of Vic, which is around 50 miles north of Barcelona. Police believe it was meant to be used as a getaway vehicle.
