Five suspected terrorists were killed today by Spanish police in the aftermath of a vehicle attack in Cambrils, which left six civilians and a police officer injured.
The suspects were reportedly linked to the first attack in Barcelona on Thursday when a van was driven into a crowd in the city's Las Ramblas district, killing 13 people and injuring more than 100.
ISIS claimed responsibility for the Las Ramblas attack, according to media sources.
Spanish Prime Minister Mariano Rajoy called the attack in the Las Ramblas area of Barcelona an act of 'jihadi terrorism'.
Rajoy was quoted by CNN as saying: "I want to also express my solidarity with all of Spain to the city of Barcelona, today hit by jihadi terrorism, like other cities have been in the world.”
In addition, an explosion that occurred at a house in the town of Alcanar on Wednesday is also being linked to the attacks in Las Ramblas and Cambrils, BBC News reported.
Police believe that explosive devices were being made at the Alcanar property.
Commenting on the attack in Barcelona, UK Prime Minister Theresa May said: “I am sickened by the senseless loss of life in Barcelona today.
"The Foreign Office is working to establish if any British nationals were involved in this appalling incident and we are in close contact with the authorities in Spain, who have our full support.
“Following the attacks in Manchester and London, Spain stood alongside the British people. Tonight, Britain stands with Spain against the evil of terrorism.”
