As I was trying to walk to Las Ramblas, I was stopped nearby at a police cordon in the tourist melting pot of beautiful, palm-filled Placa Reial.
From there, I could see armoured vehicles lining Las Ramblas and ambulances screeching to get past, a sense of panic in the air.
Soon, several plain-clothed officers in bullet-proof vests shouted at everyone to immediately evacuate the square.
Visibly stunned tourists were left wondering how this could happen in what many consider one of the safest places to visit in Europe.
Local residents could not believe this was happening in their city too.
We ran to a nearby restaurant, anxiety on the faces of everyone there, getting updates from the TV inside and mobile phones ringing endlessly.
The owner told us that police wanted him to close his premises immediately and we had to seek shelter elsewhere. The security zone was being widened as the attacker was being hunted, he said.
Barcelona, a city where tourists flock in large numbers at this time of year, often at the irritation of some locals, is in shock this evening, police helicopters still flying overhead across the city.
Spanish media report that a suspect involved in the Barcelona attack has been killed in a shootout with police on the outskirts of the city.
Spain's Prime Minister Mariano Rajoy tweets: "The terrorists will never defeat a united people who love freedom in the face of barbarism.
"All of Spain is with the victims and families."
