AN ISLAMIC preacher is being investigated for his possible role as the mastermind of the Barcelona massacre as police reveal they are still hunting three jihadis.

Spanish authorities have said they have dismantled the network of 12 terrorists, confirming they now know the identities of two bodies found in the Alcanar home that exploded as the group plotted their attacks.

The home of suspected mastermind Abdelbaki Es Satty has been searched in the wake of the two separate attacks last week, with the 45-year-old one of three still missing.

The imam had begun preaching in Ripoll around two years ago but stopped two months ago, sources at the town’s mosque said.

Police sources told Spanish media he followed the fundamentalist Salafi branch of Islam.

Detectives were said to be investigating whether he radicalised the young men who planned and carried out the atrocity on Thursday afternoon.

Es Satty’s flatmate, named only as Nodir, said the preacher had left home on Tuesday “because he was leaving for Morocco”.

Nodir has heard nothing from him since.

Police sources told El Mundo newspaper Es Satty's age and profile suggested he might be the leader of the terror cell.

The Mossos d’Esquadra would not comment on that claim.

Police are now searching for three suspects still missing - announcing on Sunday they were unsure if the wanted men were still in Spain.

The remains of at least two people were found in the Alcanar home where suspects in the Las Ramblas and Cambrils attacks allegedly tried to make explosives with butane and propane gas cylinders for the terror attacks.

Catalan police have focused their investigation on finding suspected driver 22-year-old Younes Abouyaqoub, 45-year-old mastermind, Iman Abdelbaki Es Sattyand and Youssef Aalla, brother of one of the terrorists shot in Cambrils.

Police are now carrying out DNA tests to see if any of the bodies in the rubble of the Alcanar home belong to the three men.

Officers have said they have identified the remains of two people in the house.

The three bodies do not include Mohamed Houli Chemlal, who was injured in the blast, and was arrested.

It comes as El Pais reported that the mother of suspect Abouyaaqoub attended an anti-terror rally, saying she didn't want to see anymore bloodshed, begging: "I want him to give himself up."

"I don't want them [the cell] to kill others, that's not what Islam says."

Police have poured resources into investigating the two attacks where a group of fanatics massacred 14 people and injured 130 more when vehicles were ploughed into crowds on Barcelona's famous Las Ramblas and a tourist resort Cambrils.

A Catalan government minister said the cell responsible had been "dismantled".

Five terrorists were shot dead in the wake of the Cambrils attack, with four people arrested including in Ripoll.

The names of three of the five suspects shot down by police have been revealed as being Said Aallaa, Mohamed Hychami and Moussa Oukabir - the baby-faced "jihadi" whose older brother Driss accused him of stealing his ID to hire the van that mowed down crowds was killed.

The group are thought to be known as the Tarragona Cell, a gang of jihadis who have recently returned from Syria.

But police said on Sunday that none of the members had previous criminal records of terrorism.

More information around felled suspect Moussa Oukabir has come to light in the days after the attack, with his family being probed by cops in relation to the terror attack.

His older brother, Driss Oukabir, 28, had handed himself into police after seeing his face on TV, with his name having been linked to the rented van used in the attack.

He claimed his younger brother had stolen his documentation to rent the van.

A neighbour of the family described Moussa Oukabir as "a normal, nice boy" - but concerning reports have since surfaced around his desire to "kill the infidels".

Moussa is reported to have been a regular user of a question and answer website called Kiwi, with La VanGuardia reporting the then 16-year-old answered a string of questions with disturbingly violent answers.

When asked by one user: "On your first day as absolute king of the world, what would you do?", Moussa replied: "Kill the infidels and leave only Muslims who follow the religion."

Ada Colau, the President of Catalonia, the autonomous Spanish state where Barcelona is the capital, has cancelled her holiday and is returning to the city.

Spanish Prime Minister Mariano Rajoy said the van attack was "jihadist terrorism" which required a global response.

He told a news conference in Barcelona on Friday: "Today the fight against terrorism is the principal priority for free and open societies like ours. It is a global threat and the response has to be global."

The prime minister says the residents of Paris, Nice, Brussels, Berlin and London "have experienced the same pain and uncertainty that those of Barcelona suffer today."

In a written statement, British 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."

President Donald Trump tweeted: "The United States condemns the terror attack in Barcelona, Spain, and will do whatever is necessary to help. Be tough & strong, we love you!"
