Iraq has been ''totally liberated'' from Isis, the Iraqi armed forces claimed in a statement on Saturday.
The country's Prime Minister, Haider al-Abadi, also declared the "end of the war against Isis", AFP reported.
Its armed forces were in control of the entire Iraq-Syria border, he said.
In the announcement, Lt Gen Abdul-Amir Rasheed Yar Allah said combat operations against the extremists have concluded after Iraqi forces retook control of the country's border with Syria.
The statement said: "All Iraqi lands are liberated from terrorist Daesh gangs and our forces completely control the international Iraqi-Syrian borders."
Isis fighters overran nearly a third of Iraqi territory, including Mosul, the country's second largest city, in the summer of 2014.
Over the past three-and-a-half years, Iraqi ground forces supported by the US-led coalition have retaken all the territory once held by extremists, but the group remains capable of carrying out insurgent attacks.
