Islamic State militants attacked Iraqi security forces on Friday near the two main cities of the western province of
Anbar, where authorities plan a counter-offensive against the hardline Sunni insurgents, tribal sources said.
They said the militants attacked on two fronts near Khaldiya. The
Euphrates river town lies next to a military base between the provincial capital Ramadi, seized by Islamic State in May, and their long-held bastion of Falluja.
Shi'ite militia forces, who are leading the counter-attack against Islamic State in
Anbar, and Iraqi security forces have been trying to encircle Falluja as the first stage of a military campaign to recapture the two cities.
Some of the heaviest fighting took place near the villages of
Husaybah Sharqiya,
Mudiq and
Sidiqiya, which run along the southern bank of the river west of Khaldiya, the sources said.
