An RAF drone strike against Islamic State forces in eastern Syria has "unintentionally" resulted in a civilian fatality, Defence Secretary Gavin Williamson has said.
In a statement, Mr Williamson confirmed that the "deeply regrettable" incident had occurred after the individual crossed into the strike area on a motorbike moments before the blast on 26th March.
It is the first time that the Ministry of Defence (MoD) has confirmed a civilian casualty during Britain's campaign against the terror group in Iraq and Syria.
Three IS fighters were also killed by the precision Hellfire missile as they drove in the Syrian Euphrates valley, the MoD reported.
The attack was carried out by an RAF Reaper drone, which had been tracking the trio.
The Defence Secretary has said that it was one of more than 1,600 air strikes carried out against IS targets by the RAF in Iraq and Syria.
In a statement, Mr Williamson said:
“We do everything we can to minimise the risk to civilian life from UK strikes through our rigorous targeting processes and the professionalism of UK Service personnel.
“It is therefore deeply regrettable that a UK air strike on 26 March 2018, targeting Daesh fighters in eastern Syria, resulted in an unintentional civilian fatality.
“During a strike to engage three Daesh fighters, a civilian motorbike crossed into the strike area at the last moment and it is assessed that one civilian was unintentionally killed.
“We reached this conclusion after undertaking routine and detailed post-strike analysis of all available evidence.”
An investigation will be carried out by the wider coalition, which will report “in due course”, he added.
Britain’s direct military involvement against Islamic State is limited to the skies, but troops on the ground have also been involved in training more than 60,000 members of the Iraqi security forces.
Intelligence, surveillance and reconnaissance has also been provided to coalition partners, according to the Defence Secretary.
“These strikes are undertaken in the collective self-defence of Iraq as part of the global Coalition to defeat Daesh, and at the request of the Government of Iraq," he said.
“As a result of the Coalition’s action, Daesh has lost more than 98 per cent of the territory it once occupied in Iraq and Syria, and 7.7 million people have been liberated from its rule.”
He continued that such civilian deaths “remind us of the consequences of conflict and of the heavy price that the people of Syria have paid.
"It reminds us that when we undertake military action, we must do so knowing that it can never be completely without risk.
“Such incidents will not weaken our resolve to defeat Daesh and rid the world of its poisonous ideology of hate and intolerance.
"The UK’s commitment to the Global Coalition against Daesh and to the people of Iraq and Syria will remain as strong as ever.”
