This week MPs voted for the UK to join the coalition launching air strikes against Isis in Syria.
Up until this point, the UK had already been engaged in strikes against Isis in Iraq, but has now joined the US, Australia, Bahrain, Canada, France, Jordan, Saudi Arabia, Turkey and UAE in air strike operations in Syria. Russia is conducting its own, separate mission against Isis (and allegedly other Syrian rebels).
The US and the coalition of forces have conducted a total of 8,573 strikes in Syria and Iraq as of 4pm on 1 December, as the below chart by Statista shows:
US and coalition aircraft have flown an estimated 59,015 sorties in support of operation in Iraq and Syria.
The total cost of operations in relation to Isis, since 8 August 2014, is $5.2 billion and the average daily cost is $11 million for 465 days of operations.
As of 13 November 2015, 16,075 targets had been destroyed by air strikes in Operation Inherent Resolve.
