The speed with which Iraqi forces reached the centre of Kirkuk has led the two main armed Kurdish parties to accuse each various other of “betrayal”.
Iraqi Prime Minister Haider al-Abadi said the latest operation was necessary to “protect the unity of the country”, having previously denounced the referendum as unconstitutional.
