Kurdish forces in northern Iraq have claimed their biggest victory yet against IS militants.
They say they have broken the IS siege of Mount Sinjar, where thousands of Yazidis and other displaced Iraqis have been trapped since August.
The Kurdish offensive against IS forces besieging Mount Sinjar began early on Wednesday, the BBC reported.
On the ground, about 8,000 Kurdish peshmerga fighters launched a two-pronged attack which they said had succeeded in opening a wide corridor to allow members of the Yazidi minority and others to leave.
Masrur Barzani, Chancellor of the Kurdistan Region Security Council, said the operation had been to advance from Zumar - which Kurdish forces recaptured in October - to Mount Sinjar and to rescue the Yazidi people trapped there.
“It was a very big operation and thankfully it was concluded very successfully,” he said.
Peshmerga commanders said they expected the evacuation of those trapped on the mountain to begin on Friday.
A statement from the Kurdish command said large numbers of militant fighters had fled westwards into Syria or eastwards towards Mosul, which they captured in June.
The peshmerga also said eight villages had been recaptured and about 80 militants killed in the offensive.
The town of Sinjar itself, however, to the south of the mountain, remains in IS hands, as do Mosul and the nearby town of Tal Afar.
IS captured the town of Sinjar in August forcing thousands of residents, mainly from the Yazidi sect, to flee. Many were airlifted off the nearby mountain but thousands more who came later found themselves trapped.
