Iraq's prime minister has warned so-called Islamic State to "surrender or die" as government troops close in on Mosul.
Haider al-Abadi said on state TV: "They have no choice. Either they surrender or they die."
Iraqi special forces are now about half a mile away from Mosul's eastern edge and preparing to enter the besieged city.
It is not clear when the final offensive to recapture the city will take place.
Mr al-Abadi, also the commander-in-chief of the Iraqi armed forces, added: "We will close in on Daesh [IS] from all angles and God willing we will cut the snake's head.
"They will have no way out and no way to escape."
