Three suicide attacks claimed by Islamic State killed at least 60 people in southern Iraq on Thursday, a health official and police sources said, suggesting a shift in the ultra-hardline group’s tactics since it lost control of its stronghold in Mosul.

Iraqi and Kurdish security officials say the Sunni militants are likely to wage a guerrilla war in Iraq after their self-proclaimed caliphate in Mosul collapsed.

Islamic State is also under siege in the Syrian city of Raqqa, its operational base for attacks in the Middle East and the West.

Security officials described Thursday’s attacks as an attempt to send a message to Islamic State followers that the group is still strong and can operate in other parts of Iraq following its territorial losses. Source.
