British pilots have carried out airstrikes in Syria, a Freedom of Information request has found.
The pilots were embedded with forces of allied nations - including the USA and Canada - who have been conducting air operations against so-called Islamic State targets.
Officials wouldn't give exact figures but said the number of personnel involved were in single figures and none were currently taking part in airstrikes.
In 2013, MPs led by then-Labour leader Ed Miliband voted against military action in Syria and parliamentary authority only allows British forces to strike at targets in neighbouring Iraq.
The MoD insists that any personnel embedded with a foreign nations' military are effectively under the control of that country, meaning no rulings from the House of Commons have been breached.
ritish troops are regularly embedded in other nations' forces and have operated under US command since the 1950s, including in recent operations in Afghanistan, Iraq and Libya.
The MoD agrees each deployment and continually monitors the permissions granted to embedded troops.
UK forces are taking part in surveillance and air-to-air refuelling operations over Syria, and in the wake of the murder of 30 Britons in a terror attack in Tunisia last month, David Cameron and Defence Secretary Michael Fallon made clear they are considering extending air strikes against IS into the country.
They have indicated that they would seek MPs' approval for an extension of air strikes into Syria, but no vote is expected before the autumn.
Details of British personnel's involvement in strikes by allied nations' forces were revealed by a Freedom of Information request from pressure group Reprieve.
