>> Several people dead and dozens more wounded after a van ploughed into a crowd in Barcelona. Police are treating the incident Thursday as a terrorist attack. Islamic state has claimed responsibility. Reuters correspondent Angus Berwick is in Spain.>> There is a lot of confusion on the ground. What is confirmed is that police have arrested two people, who they say may be connected to the incident.
More than 90 people were hospitalized in the attack.>> The incident occurred on the main street in the Las Ramblas area, a magnet for tourists. An estimated 11 million people visit the city every year. Separately, police said the van attack appeared to be linked to an explosion at a house in Alcinar in the early hours of Thursday, in which one person died and another was injured.
The crash would add to a wave of militant attacks across Europe, many using vehicles as their weapon. Over 100 people have been killed in the last year using this tactic, which Spain had so far avoided. Thursday's attack was the deadliest in Spain since 2004, when Islamist militants placed bombs on commuter trains in Madrid, killing 191 people and wounding more than 1,800.
