Theresa May congratulates Iraq's Haider al-Abadi for victory over Islamic State, warns group is 'not yet defeated'

London: British prime minister Theresa May on Saturday congratulated her Iraqi counterpart Haider al-Abadi over the Islamic State victory, but warned the militant group is “not yet defeated”. Extremists are “still pose a threat to Iraq, including from over the Syrian border”, May said in a statement issued here after the Iraqi prime minister claimed an end to the fight against the terrorist group earlier Saturday, Xinhua news agency reported.

Islamic State rapidly captured large territories in Iraq and Syria and declared a caliphate in 2014. The group controlled more than 34,000 square miles of territory from the Mediterranean coast to south of Baghdad. The campaign to eradicate the Islamic State took more than three years and about 25,000 coalition air strikes. Iraqi forces have increasingly been pushing Islamic State out of the country over the past few months. Troops last month retook the town of Rawa, one of Islamic State’s last footholds in the country. At that point, only pockets of Islamic State resistance remained.
