A 14-year-old British boy on holiday with his family in Italy died in the earthquake which struck on Wednesday.
A British couple staying in the same holiday home in Amatrice were also killed in the 6.2 magnitude quake, which has taken the lives of at least 268 people.
Italy has declared a state of emergency in the regions worst hit by the earthquake, many of which are popular holiday locations.
The boy who was killed has been identified by the Foreign Office as Marcos Burnett from London.
According to the Mirror, his parents were injured in the quake and were initially taken to separate hospitals, but were reunited before being told the tragic news of their son’s death.
Their daughter survived and is now with other family members who flew out to help.
Another couple staying in the same house – Will Henniker-Gotley, 55, and his wife Maria, 51, from Stockwell in London – were also killed.
The Foreign and Commonwealth Office said: "The families have paid tribute to the tireless work of the Italian rescue workers and hospital staff and expressed their gratitude for the love and support they have received from the Italian people."
The regions affected include Lazio, Umbria, Marche and Abruzzo. The FCO advised anyone in the area to follow the advice of the local authorities.
It said Civil Protection in Italy have activated an international hotline +39 06 828 888 50 for information. Within Italy, Brits can also call 8008 40840 or 808 555 for the dedicated Lazio line.
