The Defence Secretary has praised Britain's armed forces for their work in fighting Islamic State (IS) extremists during a visit to Cyprus.
Michael Fallon told the 400 service personnel based at RAF Akrotiri he was "proud" of their role in helping the Iraqi government defend itself against the threat of IS.
"While this fight will take time, the coalition's air strikes are having a direct effect in supporting Iraqi ground operations against IS," Fallon said.
"In the north, areas around Mount Sinjar have been retaken, bringing relief to the local Yazidi population and applying pressure to IS forces in Mosul. In the south, Iraqi forces operations are beginning to push back ISIL."

Islamic State (IS) has released 19 Christians who were among the more than 220 people the militants took captive in north-eastern Syria last week.

The Britain-based Syrian Observatory for Human Rights activist group also reported that 19 Christians had been freed.
It was not immediately clear why the Islamic State group released them.
The fate of the remaining Christian captives is unclear.
