Islamic State militants seeking to "subvert and destroy the values of democracy" must be defeated, the Foreign Secretary has warned - saying action was crucial "for the security of Britain."
Foreign ministers from around the world were due to fly in to London today for a top-level summit discussing how to take the terror group down.
The Prime Minister has promised the UK will do "everything [it] can" to stop people travelling to Iraq to join Islamic State fighters.
Speaking in No. 10, David Cameron told his Iraqi counterpart Haider al-Abadi:
Amid talk of prisoner exchange, it's worth bearing in mind that IS militants are not explicitly saying they're ready to release hostages.
Iraq is running out of money to fight the terrorists of the self-styled Islamic State - because of falling revenues from lower oil prices.
