18.54 IBTimes UK live coverage of the crisis in Iraq ends here for today. Come back for more updates tomorrow 8.00 BST.

18.42 Germany has urged its citizens to immediately leave parts of Iraq, including Baghdad.

The Foreign Ministry says Germans should leave the governorates of Anbar, Ninevah and Salah al-Din and expressed concern about the situation in Diyala and Kirkuk governorates.

18.24 France's foreign minister urged the international community to take swift action in Iraq, in a series of tweets.

Laurent Fabius said he is very concerned by the situation in the country and the advance of Isis that, he wrote: "poses a serious threat to the stability of the region and puts into danger the unity and sovereignty of Iraq."

18.13 More from Obama, who spoke about Iraq following a White House meeting with Australian Prime Minister Tony Abbott.

The US president said Baghdad Iraq will need additional assistance to push back the insurgency and added he is watching the situation with concern and wants to ensure that jihadists do not get a foothold.

Obama added that part lack of trust between moderate Shia and Sunni leaders is [artially to blame for Iraq weak response to Isis's advance.

"We have not seen trust develop between moderate Shia and Sunni leaders within Iraq," Obama said, adding this "accounts for some of the weakness of the state".

17.51 President Barack Obama said he doesn't rule out anything for US responses to the crisis in Iraq.

"[We are] looking at all options in helping the Iraqi government face the growing insurgency," Obama was quoted as saying by Reuters.

17.10 An official in the Turkish prime minister's office said Ankara is negotiating the release of 80 Turkish nationals that have been taken hostage by Isis in Mosul.

Turkish officials are said to be talking directly with the Jihadist militants in the Iraqi city. The captives include 49 people seized in the Turkish consulate.

16.08 There are reports that Isis has discussed the possibility of extending the group's control beyond Syria and Iraq. One of the ideas is focusing Isis's efforts on Jordan, where other Islamist movements have a significant presence. Jordanian political analyst Oraib al-Rantawi considers the jihadi threat imminent:

"We in Jordan cannot afford the luxury of just waiting and monitoring. The danger is getting closer to our bedrooms. It has become a strategic danger; it is no longer a security threat from groups or cells. We must start thinking outside the box. The time has come to increase coordination and cooperation with the regimes in Baghdad and Damascus to contain the crawling of extremism and terrorism."

Isis see Jordan's Western-backed King Abdullah as an enemy and in a video posted on YouTube they threatened to "slaughter" him. Some jihadis who appear in the video were Jordanian citizens who tore up their passports in front of the camera.

15.50 Iraq has launched a campaign of airstrikes on Islamic State of Iraq and al-Shams (Isis) positions in Mosul following the capture of the city. Read more here.

15.34 Here's an interesting assessment on the Iraqi crisis by Ali Soufan group:

A great deal depends on what the Iraqi army does in the next few days in terms of keeping ISIS and band-wagon groups like JRTN away from Baghdad. Just as there is little probability ISIS will remain in control of Mosul, there is little probability of ISIS taking over the Shi'a-dominated capital. But, the finer point is that ISIS has released over 2,000 prisoners from jails in Mosul, captured an unknown but likely large number of modern weapons, and seized an unknown but likely very substantial amount—some reports indicate over $400 million—of money from banks. If ISIS can threaten the capital, however briefly, it will provide the group with something as powerful as weapons and money: momentum and a sense, even if fleeting, of inevitability.
