London's Grenfell Tower was lit up in green overnight on Thursday (June 14) alongside other buildings in London to mark the first anniversary of the tower block fire, which killed 71 people.

Grenfell Tower, a social housing block that was home to a close-knit, ethnically diverse community, was engulfed by flames in the middle of the night of June 14, 2017, in Britain's deadliest domestic fire since World War Two.

In the run-up to the anniversary, the top floors of the charred ruins of the building have been covered with white sheeting displaying large green hearts - the symbol of the tragedy - and the words "Grenfell Forever In Our Hearts".

Buildings across Britain, including Prime Minister Theresa May's official residence Number 10 Downing Street and the London Eye, were also lit up in green overnight in honor of the victims.
