BAGHDAD (AFP) - Iraqi Prime Minister Haider al-Abadi declared victory Sunday (July 9) in the "liberated" city of Mosul, the Islamic State in Iraq and Syria's (ISIS) last urban stronghold in Iraq, as the group's Syria bastion Raqqa is surrounded.

Here are key dates in the group's history and its battle for Mosul:

ISIS created

April 9, 2013: Al-Qaeda in Iraq chief Abu Bakr al-Baghdadi says Al-Nusra Front, an extremist group battling the Syrian regime, belongs to his Islamic State of Iraq and the Levant (ISIL) and is fighting for an Islamic state in Syria.

A day later, Al-Nusra pledges allegiance to Al-Qaeda chief Ayman al-Zawahiri, distancing itself from Baghdadi. In early 2014 Al-Qaeda disavows ISIL completely.

Syria's Raqqa falls

Jan 14, 2014: ISIL conquers Raqqa city in northern Syria after fierce fighting with rival rebels. Raqqa, the first provincial capital to fall entirely from regime hands, becomes the jihadists' Syrian stronghold.

Iraq's Mosul captured

The battle for Raqqa

Nov 5, 2016: The SDF launches an operation to capture Raqqa.

Key dates in the Mosul offensive:

The battle begins

Oct 17, 2016: Iraqi forces launch the assault to recapture Iraq's second city, conquered by ISIS in June 2014. A month later the extremist group's supremo Abu Bakr al-Baghdadi made his only public appearance in Mosul, to urge Muslims worldwide to move to the recently proclaimed "caliphate" straddling Iraq and Syria.

Tens of thousands of army, police and counter-terrorism troops are thrown into the long-awaited offensive with crucial support from a US-led coalition.

In two weeks dozens of surrounding localities are recaptured, including the Christian town of Qaraqosh around 15km from Mosul.

Entering Mosul

Nov 1, 2016: The army says it has entered Mosul city for the first time since 2014.
