The UK reopened its embassy in Libya on Sunday after an eight-year hiatus.
“This is a demonstration of the UK’s commitment to the whole of Libya. I am proud our work touches the lives of Libyans across the whole country already,” said Ambassador Caroline Hurndall on Twitter.
UK-Libya relations are deep and historical, she added.
The UK had closed its diplomatic missions in Libya in 2014 amid intense armed clashes in the country.
