The leader of the Islamic State, formerly Isis, has released the first audiotape calling for jihad since the group renamed. The group is currently battling Iraqi forces across large parts of the country.
President Obama voiced his concerns about Isis rebels returning to wage war in the west as Islamist militants continued to battle government forces in Iraq.
The US leader said: "We've seen Europeans who are sympathetic to their cause travelling into Syria and now may travel into Iraq getting battle hardened. Then they come back. They've got European passports. They don't need a visa to get into the United States."
Meanwhile, Iraq took deliver of some second hand fighter jets which they hope will help them to halt the advance of the militant fighters.
The Foreign Secretary has been clear on the threat of Isis, but he has ruled out the prospect of any UK military involvement in the crisis.
Iraq’s foreign minister, Hoshyar Zebari, is a natural diplomat. Polite, immaculately dressed, and blessed with a great memory.
Isis has paraded military equipment in Mosul it captured from when the Iraqi army fled in what some see as a "nightmare scenario."
