Six extra Typhoon jets are en route to RAF Akrotiri, the Defence Minister confirmed.
The jets took off from RAF Lossiemouth as Michael Fallon announced he was doubling the strike force against IS in Syria.
Two more Tornado jets are also being sent to the UK RAF base in Cyprus after MPs voted to approve military action targeting IS in Syria.
The shadow chancellor warned it could foster another generation of militants determined to commit a Paris-style terror attack.
The Defence Secretary has warned the RAF that the fight against Islamic State will not be short or simple.
Officers were posted outside the constituency office of Neil Coyle, the Labour MP for Bermondsey & Old Southwark.
