A young Donegal woman has spoken of her horror after seeing hundreds of people fleeing from the scene of yesterday's horrific truck attack in Barcelona.

Translator Amy McColgan from Hawthorn Heights in Letterkenny, is based just two hundred metres from yesterday’s attack at Las Ramblas which is understood to have claimed the lives of a number of people.

It is understood a van ploughed through a crowd of people before the driver fled on foot.

Amy, 27, has told how she heard the voices of hundreds of people screaming in shock as they fled the attack outside her office at Trans Perfect.

She told Donegal Daily “We were at our desks working on translation projects when we began to hear a lot of raised voices and people fleeing away from the Las Ramblas. It was weird because every now and again you would hear people screaming.

“At that stage we still didn’t know what had happened because we cannot see the scene of the attack from our offices.

“We knew something had happened but it wasn’t until we went online that we realised there had been what seems to be a terrorist attack,” she said.

Amy is still in her offices and herself and her colleagues have been told to stay inside the building.

“We have been told there could be more of them around and not to go outside the building. I don’t know when we are going to be able to leave,” she said.

Amy, who moved to Barcelona a number of months ago, said she has been left stunned by the attack on the city.

“Barcelona is such a chilled city and I never thought in my life that it would be the focus of an attack.

“It’s a beautiful city and it just crowded with people at this time of year. I guess that’s one of the reasons why they targeted it,” she said.

Amy revealed how she texted her mum and dad Jennifer and John to let them know that she was okay directly after the attack.

Amy recently moved 5kms outside of Barcelona to the suburb of San Marti but all the Metros have been closed down.

However, she revealed how her colleagues have already offer herself and other people beds for the night.

“People have been so good already and have offered to allow those of us who live outside of the city to stay on their sofas,” she said.
