US Airstrikes Pound ISIS Militants Firing At Iraqi Yadizis

American warplanes pounded extremist Sunni fighters in northern Iraq on Saturday in what officials described as an effort to defend minority Yazidis being indiscriminately attacked, strikes that came just as President Barack Obama warned of an extended air campaign against the terror group.

The series of airstrikes began with a mix of fighter jets and drones that targeted militants firing on Yazidis near the town of Sinjar, where fighters with the Islamic State, formerly known as the Islamic State of Iraq and Syria, forced tens of thousands into hiding on nearby Sinjar Mountain.

The airstrikes were the first in the Sinjar area since Obama authorized targeted attacks to protect Americans and Iraqi minorities from an ISIS advance threatening the Kurdish regional capital of Irbil.

Given that Iraqi security forces still need time to ramp up and Iraqi politicians need space to form to form a more inclusive government to whittle Sunni support for ISIS, this is going to be a long-term project, Obama said from the White House South Lawn.

The airstrikes on Saturday began at about 11:20 a.m. ET, with the targeting of two ISIS armored personnel carriers (APCs) firing on Yazidis, according to a statement released by the U.S. Central Command. Another two rounds of airstrikes were carried out about 20 minutes later after more ISIS vehicles, primarily APCs, moved into the area, the statement said.

A fourth round of airstrikes was carried out more than three hours later when U.S. aircraft struck another ISIS armored vehicle, it said.

At the same time, health and civil defense officials said U.S. warplanes targeted ISIS fighters near the town of Makhmur, where the group has been launching attacks on the outskirts of Irbil.

The Pentagon declined to comment on the claims by Iraqi health and civil defense officials in Mosul, who told CNN the airstrikes killed at least 16 of the fighters.

Running out of time

Meanwhile, the UK and France has said it will join the United States in humanitarian airdrops for hundreds of thousands of Iraqis on the run ahead of a brutal ISIS advance.

On Saturday, the United States carried out another round of airdrops. Three cargo aircraft supported by U.S. fighter jets dropped 3,804 gallons of fresh drinking water and 16,128 ready-to-eat meals, the military said.

But a United Nations official said airstrikes and humanitarian airdrops arent enough for the estimated 40,000 minority Yazidis, who are trapped on Mount Sinjar and hiding from ISIS fighters who have said they will kill the group.

Only about 100 to 150 people a day have been able to be airlifted by Iraqi security forces off the mountain, said Marizio Babille of UNICEF.

We are running out of time for thousands who can obviously not be reached by these airdrops, he said, adding that UNICEF is appealing for the international support to open and secure a humanitarian corridor over land.

Dozens, including 60 children, according to UNICEF have died on the mountain where the Yazidis are battling extreme temperatures and a lack of food and water.

American planes also have twice dropped food and other supplies to thousands of Yazidis, members of a minority group that fled to a northern Iraqi mountain after ISIS militants overran their town, Obama said Saturday.

U.S. aircraft are poised to strike ISIS militants who have surrounded the mountain, Obama said. Any such strikes would support Kurdish forces efforts to free the Yazidis, he said.

The airstrikes have ramped up Americas involvement in Iraq where ISIS is seizing control of towns and key infrastructure even as it celebrates its own slaughter along the way.

The United States has hundreds of military personnel in Iraq, including advisers sent in recent weeks to coordinate with Iraqi and Kurdish military officials in response to the ISIS rampage. The USS George H.W. Bush and other Navy ships also are in the region.

Obama indicated Saturday the United States interests in targeting ISIS went well beyond protecting U.S. personnel and Iraqi minorities.

My team has been vigilant about foreign fighters and jihadists gathering in Syria and now Iraq, who might potentially launch attacks outside of the region against Western targets and U.S. targets, he said. So theres going to be a counterterrorism element that we are already preparing for and have been working diligently on for a long time now.
