The firm launched an emergency hotline and email address and set up a response team to contact all their customers in the area to ensure their safety and bring them home.

It has also been in contact with hundreds of other holidaymakers who were due to jet off to the African country, but have since decided to cancel or re-arrange, with the travel operator offering alternative destinations across Europe.

However chief executive Sharon Munro says staff are still in shock over what has happened, and says that while non of their customers were victims, the horrific scenes in Sousse have had a massive impact on them.

Speaking to The News she said: “This has been a horrific incident, and as soon as news began to filter through we set up an emergency team in our Glasgow branch, with a hotline and email address, so that our customers in the area could contact us.

“We had customers in the resort, not in the affected hotels, but they heard and saw horrific things none the less and they are extremely upset.

“Our staff are still in shock, but they worked through the night to contact our customers and get them repatriated home, some decided to stay.

“We have also contacted customers who were booked to fly to the area, and discussed with them what their options are, and we have even been changing them to some of our private charters in other destinations such as Barcelona and Venice.

“We are still working through our customers by their departure date.

“However some still wanted to go to Tunisia — I think it’s a stiff upper lip and the mentality that they won’t be scared off.” Meanwhile, a Renfrewshire taxi driver and his family have made a safe return home after being caught up in the aftermath of the Tunisia terrorism attack.

Ricky Wilson, from Johnstone, arrived home late on Monday night with his wife Angela and daughters Lisa and Kasia after flying into Manchester.

The day after Friday’s horrifying massacre, Ricky took to Facebook to let friends and family know they were safe.

He said there was a heavy military presence at the beach where 38 people lost their lives, most of whom were British.

They had been enjoying a wonderful time in the sun-kissed Mediterranean resort until all hell broke loose on Friday when a gunman started firing at holidaymakers on the beach.

It’s understood at least 22 British citizens are among the dead but officials say that number is expected to rise as victims are formally identified.

It has been confirmed that a Perth couple Billy and Lisa Graham were among the victims.

Ricky, 46, and his family were among the lucky ones to have avoided the carnage.

As the extent of the tragedy unfolded, Ricky told friends back home in Johnstone: “A wee update on our situation out here. Firstly, we’re all good and safe and they’ve got armed guards at the gate and beach. The police and army have a high profile drive-by every 10 minutes. Advice is to stay in the hotel and not to venture out.

“No words to describe these animals. It happened just along the beach from us, but we’re good.” Ricky later told The News they were finding it difficult to obtain clear information from their tour operator Thomas Cook but said the Tunisian people were going out of their way to make sure they were safe.

Meanwhile, a Paisley man was also among the British tourists caught up in the horror.

Gordon Hughes was staying at the El Mouradi Club Kantaoui hotel close to the beach where tourists lost their lives in a hail of gunfire.

Mr Hughes posted a photo of the beach and a message on social media, which said: “Will never forget this beach in a hurry. We have just been told 38 dead and 36 injured.” It’s understood Mr Hughes has now returned home to the UK in the wake of the atrocity.

Also among those caught up in the chaos was Barrhead man Darren McCullagh who was on holiday with his girlfriend.

In an interview with Sky News Darren’s mother Moya said her son and his girlfriend witnessed horrific scenes at the beach where the terrorists struck.

She said the couple had taken refuge in a hotel laundry room as the chaos unfolded.

A member of his family later told our reporter the 23-year-old was “safe and well at this moment in time”.

It’s understood that as many as 38 people have been killed in the terrorist violence with 22 British citizens among the bodies identified so far.

Prime minister David Cameron told a press conference the public can expect the British death toll to rise.

Islamic State extremists have claimed responsibility for the massacre at the Mediterranean resort.

Tunisia officials have released an image of a 23-year-old man named Seifeddine Rezugi who is believed to be the gunmen who was shot dead by police.

But yesterday, fears emerged that two more gunmen may have been involved in the sickening attacks.

One accomplice may be on the run and it’s believed another may have been shot dead.

Meanwhile, British tourists arrived back in the UK on Monday with many cheering with relief upon arrival at Gatwick Airport.

However, many more UK residents remain in Tunisia as they try to arrange flights home.

Nicola Sturgeon has paid tribute to the Scottish victims of the Tunisia attack.

Scotland’s First Minister said: “The Scottish Government, Police Scotland and our partners are doing everything to support those who may be affected by this horrific attack and their families.

“The victims and their families are foremost in our thoughts.” Sturgeon said flags at all the Scottish Government buildings are flying at half mast as a mark of respect.

A Scottish Government spokeswoman said: “We are closely monitoring the horrifying situation in Tunisia and our thoughts are with those affected and families worried about loved ones.

“The Scottish Government is in contact with the Foreign and Commonwealth Office and we stand ready to offer assistance.” Prime Minister David Cameron said he is “sickened” by the attacks and other recent atrocities in France and Kuwait.

The Foreign Office said people in the UK concerned about relatives in Tunisia should call them on 0207 208 1500.

A spokesman said any British nationals in Tunisia should make contact with the embassy there.
