Islamic State steps up counter-attacks as fighting edges closer to Mosul
Islamic State expanded its attacks on October 24 against the army and Kurdish forces across Iraq, trying to relieve pressure on the militant group's defenses around Mosul, its last major urban stronghold in the country.
About 80 Islamic State-held villages and towns have been retaken in the first week of the offensive, bringing Iraqi and Kurdish forces closer to the edge of the city itself - where the battle will be hardest fought.
The Mosul campaign, which aims to crush the Iraqi half of Islamic State's declared caliphate in Iraq and Syria, may become the biggest battle yet in the 13 years of turmoil triggered by the US-led invasion of Iraq in 2003, and could require a massive humanitarian relief operation.
Some 1.5 million residents remain in the city and worst-case forecasts see up to a million being uprooted, according to the United Nations. UN aid agencies said the fighting has so far forced about 7,400 to flee their homes.
In a series of counter-attacks on far-flung targets across Iraq since October 21, Islamic State fighters have hit Kirkuk, the north's main oil city, the town of Rutba that controls the road from Baghdad to Jordan and Syria, and Sinjar, a region west of Mosul inhabited by the persecuted Yazidi minority.
