Britain launches Syrian airstrikes less than hour after Parliament vote

British fighter jets have wasted no time in pounding ISIL targets in Syria, launching less than an hour after Parliament voted in favour of airstrikes.

Loaded with precision guided Brimstone missiles, two Tornado jets took off from a RAF base in Cyprus only 57 minutes after MPs voted to join the action against ISIL.

The jets returned to base three hours later, the BBC reports.

The British Ministry of Defence is yet to comment on the success of the operation and what targets were hit.

Britain was already carrying out airstrikes against ISIL targets in neighbouring Iraq.

The vote for Syrian airstrikes was won 397 votes to 223, after a marathon and emotion-filled 10 hour debate in the House of Commons.

"These terrorists are plotting to kill us and to radicalise our children," Prime Minister David Cameron said during the debate.

“These women-raping, Muslim-murdering, medieval monsters - they are hijacking the peaceful religion of Islam for their warped ends."

Opposition Labour leader Jeremy Corbyn voted against military action, saying Britain becoming involved could lead to terrorist attacks on home soil, as well as raising concerns about potential civilian deaths.

The conscious vote revealed a major split in Labour with 66 voting in favour, compared to 153 against.

Just seven Conservatives voted against military action, while 333 voted yes.
