On 26 June, a lone gunman with potential links to the terrorist group ISIS carried out an attack on a Tunisian beach resort, killing 38 people.
The gunman, who was shot dead by police, has been identified as Seifeddine Rezgui, 23.
In a speech given the day after the attack, prime minister David Cameron warned that "many of those killed" in Tunisia were British, and said he would hold a meeting with the government's emergency Cobra committee to formulate a response.
Foreign secretary Philip Hammond later confirmed 30 British tourists had been killed.
Here are some of the victims of the attack:
Lorna Carty, Robinstown, County Meath, Ireland
Carty travelled to Tunisia with her husband, Declan, following his heart operation. The couple had been given the holiday as a present, friends told the Irish Times.
Carty went to the beach on her own while her husband stayed in the hotel room. They were due to leave Tunisia hours after the attack took place.
Sources told MailOnline that Declan had been able to escape the scene without harm but was "devastated" after hearing about his wife's death. Carty's son has travelled to Tunisia in order to be with his father.
A friend told the website: "Declan was in the hotel and Lorna went out to get a last bit of sun before leaving... When he heard all the commotion he went out, then he recognised the towel and the blood on it... He's devastated."
Carly Lovett, 24, Lincolnshire
Lovett (above right), from Gainsborough in Lincolnshire, is said to have travelled to Tunisia with her fiancé, Liam Moore (above left), who is believed to still be in the country.

Kyle Leeman, 23, a friend, told the paper she was a "kind and outgoing person".

Evans worked for the council for 32 years, and was on the first day of his holiday in Tunisia. He was due to travel to France shortly afterwards, according to the Birmingham Mail.
In a statement last week, Sandwell council leader Darren Cooper said: "Adrian Evans was a very popular and long-serving employee, who was manager of our Gas Services Team.
"We are absolutely devastated for Adrian's family, friends and colleagues and our thoughts are with them and all those affected by this tragedy."
