San Francisco wife in desperate search for her husband in the wake of the Barcelona terror attack - after he went to find a toilet moments before a van rammed into crowds on Las Ramblas

• Jared Tucker, 43, was in Las Ramblas area of Barcelona during the terror attack
• 13 are dead, around 100 wounded after van ploughed through crowds of people
• Tucker and wife Heidi Nunez were shopping for souvenirs when chaos unfolded
• She fled the area with a friend unscathed but later returned to try and find him

A San Francisco man who was in the Barcelona tourist district when a terrorist ploughed a van through dozens of bystanders has not been seen since.

Jared Tucker, 43, was in Las Ramblas area with his wife Heidi Nunez when they became separated in the chaos of the attack which left 13 dead and more than 100 injured.

Hours after the first attack, five jihadis in fake suicide vests were shot dead by police after launching a second onslaught in Cambrils, 70 miles from Barcelona.

Tucker's brother-in-law Kalani Kalnui says they were buying souvenirs on the sidewalk when the vehicle came rampaging through the street packed with holidaymakers.

He told ABC News: 'He left, and seconds later she was pushed over into the kiosk and she was disoriented trying to find him. Police evacuated... her from the area.'

Kalnui says Nunez was able to flee the area unscathed but went back to try and find her husband.

Nunez is said to have contacted hospitals, temporary rescue centers and the Red Cross to try and find Tucker.

She was able to get out of the area with the friend they were staying with in Barcelona, who came and picked her up.'

'She's not able to find out information,' Kalnui said. '[Officials] haven't posted anything as far as names who are injured or deceased.'

Spanish officials have said the dead and injured from the attack, in which a jihadi drove a van through crowds of people at 60mph, span 24 different countries.

Police are today hunting for Europe's most wanted man Moussa Oukabir, an 18-year-old Moroccan-born teenager believed to have been the driver.

His brother's ID was used to rent up to three vans, including the one in the attack, but he has since handed himself into police and denied any involvement.

Oukabir fled on foot, but it is unclear if he joined the Cambrils attack which police are now linking to the one in Las Ramblas.

Police believe the terror cell lived in the resort town of Alcanar, 120 miles south of Barcelona, where a house-cum-bomb factory packed with gas canisters was destroyed in an explosion on Wednesday killing one man and injuring another.

Catalonia's interior minister, Joaquim Forn, tells Onda Cero radio that the suspects in Cambrils were driving in an Audi 3 and began plowing down people near the boardwalk.

A police car was damaged and an officer was among the six people injured in the second attack.

Forn says the suspects killed in a subsequent shootout with police were wearing fake bomb belts. He says the belts were very well made, and that authorities only determined they were phony after a controlled explosion.

Seven people including a policeman were injured in Cambrils on the Costa Dorada where the Jihadis' Audi A3 car overturned after ploughing through crowds on the seafront.

The terrorists bailed out clutching knives and were seen smiling and shouting taunts at police who shot them dead in the street at around 1am.

Tourists ran for their lives and hid on the beach or in seafront bars as gunshots rang out around them and holidaymaker Fitzroy Davies, from Wolverhampton, described how police gunned down one of the Cambrils attackers but he got up again and started 'ranting and raving'.

He said: 'He must have been on drugs. He was taunting, smiling, laughing and he carried on walking to the police, and then they gave it to him again, a couple more shots and then he fell to the ground'.
