US President Donald Trump today welcomed the end and defeat of a "hawkish", promising that the United States would remain vigilant about the extremist organization.

"I am pleased to announce that the United States, in cooperation with our allies in the international coalition ... including the Iraqi security forces and the Syrian Democratic Forces, liberated all the territory controlled by the organization in Syria and Iraq, 100 percent," Trump said in a statement.

"We will remain vigilant ... until the defeat of the organization wherever it is, we will continue to work with our partners and allies to crush completely extremist terrorists," Trump said.

"To all the young people on the Internet who believe in the propaganda of an organization," he said, "death awaits you if you join them."

The Syrian Democratic Forces announced today the total elimination of the "call" after the control of the last pockets on the eastern banks of the Euphrates River, thus bringing about five years during which the extremist organization succeeded in provoking terror.

The Syrian Democratic Forces, backed by the US-led international coalition, lifted their yellow flag on a building inside the last spot under the control of the organization in the town of Baguoz.

"The Syrian Democratic Forces announce the total elimination of the organization and its loss of 100 percent of its control territory," said Mustafa Bali, director of the media center in Kassad.

British Prime Minister Theresa Mae called the liberation of the last spot under the control of the pope a "historic turning point" at a time when French President Emmanuel Macaron said "a great danger has come from our country." At the same time, "the threat remains, Lasts".
