'Jihadi John' air strike: what we know now

Prime minister David Cameron has said "we cannot yet be certain" that the strike against 'Jihadi John' was successful, in a statement outside Downing Street on Friday.

...This was an act of self defence. It was the right thing to do.

Britian and our allies will not rest until we have defeated this evil terrorist death cult, and the poisonous ideology on which it feeds.

• US military sources have confirmed there is a 'high degree of certainty' that Mohammed Emwazi, the British Isis executioner known as 'Jihadi John', has been killed in an air strike.

• The US drone strike was launched near Raqqa in northern Syria, the self-styled caliphate's 'capital'

• It targeted a vehicle convoy that US intelligence believed was carrying 27-year-old Emwazi. One other person is believed to have been killed.

• Emwazi rose to notoriety in August 2014 when Isis released a video of him beheading journalist James Foley

• It later emerged that the Kuwaiti-born British national had been known to British intelligence services, but managed to travel to Syria in 2013
