The UK Foreign Office Minister Tobias Elwood has described the terror attack in Tunisia as an "act of evil", as the number of confirmed British nationals killed reaches 15.

Elwood described the attack as the most significant terror attack on British nationals since the July 7 2005 terror attacks in London.

He also warned that the number is likely to rise as a number of British nationals were seriously injured during the attack.

This comes as Adrian Evans has been named as the second British citizen to have been killed. He worked for Sandwell Council in the West Midlands as a manager in the gas services department.

Reports suggest that he was gunned down on the beach along with is nephew Joel Richards, 22, two of his relatives.

The first victim to be named was 24-year-old photographer and blogger Carly Lovett. She had gone away with her fiancée Liam Moore, who is understood to have survived the brutal attack. The couple had only got engaged in December.

Lovett tweeted on Wednesday: "Definitely leaving in like three hours and definitely am not finished packing." Her Twitter account quickly filled up with people sending Tweets their condolences to Carly.

The Foreign Office has not confirmed the names of any of the Britons who died in Friday's massacre.

However, Ireland has confirmed Lorna Carty from Robinstown, County Meath, died after she went to the beach by herself. She had travelled to Tunisia with her husband, who was recovering from heart surgery. The couple were due to leave Tunisia just hours after the massacre.

Her husband is thought to have escaped without injury but he is "absolutely distraught".

The Scottish first minister Nicola Sturgeon warned her citizens that they should expect Scottish nationals to be among the dead.

At the time of writing, three Belgians, a German and an unknown number of French nationals had been confirmed dead.

Tour companies and airlines have been flying tourists out of Tunisia and home to the UK, with a number of airlines and tour operators cancelling bookings to Tunisia.
