Battle for Mosul Begins

On Monday 17 October, an Iraqi operation to recapture the city of Mosul, which is the last stronghold of the so-called Islamic State (IS) in the country, began, with official reporting that pro-government forces have already made gains.

The start of the operation was announced by Prime Minister Haider al-Abadi in a televised address in the early hours of Monday (local time). Shortly afterwards, artillery began firing on the city in what is a long-awaited assault from Kurdish peshmerga, Iraqi government and allied forces. On the ground sources reported tanks moving towards the city, which has been held by IS since 2014, with one source disclosing that Kurdish tanks have closed the gap with IS position on about 300m. Kurdish forces have also disclosed that they have retaken a number of villages in their advance while pro-government forces are attacking an airbase in Qayyarah, located about 60 km (37 miles) to the south, which was recaptured in August. The US-led coalition that is fighting IS is backing the assault with air strikes. Analysts have warning that the operation is complex, adding that it could last for weeks, if not months.

Who is Fighting?

About 30,000 pro-government troops are involved in the operation, with the main assault being led by Iraqi army troops who are based south of Mosul. About 4,000 Kurdish peshmerga milita have begun clearing villages in the east. Sunni tribal fighters and Shia-led paramilitary forces are also due to take part, while planes from the US-led coalition against IS are providing air support. US Special Operations personnel are advising forces on the ground and elite Iraq counterterrorism forces are expected to join in th coming days. It is estimated that between 4,000 – 8000 IS fighters are defending the city.

Importance of Mosul

Mosul, which is the oil-rich capital of Nineveh province, was Iraq’s second-largest city before IS militants overran it in June 2014. Its capture became a symbol of the group’s rise as a major force and its ability to capture and hold territory. It was there that IS leader Abu Bakr al-Baghdadi proclaimed a “caliphate” in parts of Iraq and neighbouring Syria. The city was one of the country’s most diverse, and comprised of ethnic Sunni Arabs, Kurds, Assyrians and Turkmens as well as a number of religious minorities. While members of those minorities largely fled the onslaught by IS, many local Sunni Arabs initially welcomed the militants as they were angered by the sectarian politics of the previous Shia Arab-led central government. However after two years of brutal IS rule, opposition has grown inside the city.
