Iraqi security officials say they have received custody of a second batch of 150 Iraqi Islamic State fighters from U.S.-backed forces in Syria.
Two officials, speaking on the condition of anonymity because of media regulations, said the Syrian Democratic Forces handed over Iraqi nationals on Saturday night.
The fighters will be interrogated about their participation with the jihadist group, the officials said.
The SDF has told Iraqi authorities it has captured 650 Iraqi militants in the fighting for Baghouz, an Islamic State-held village in eastern Syria, according to the officials.
On Thursday, the SDF handed over 150 militants, in the first significant transfer to Iraq.
Iraqi Prime Minister Adel Abdul-Mahdi has said Iraq is also preparing to receive thousands of Iraqi women and children living in SDF camps in Syria.
Meanwhile, Kurdish-led forces in Syria said they would complete the evacuation of thousands of civilians from Islamic State's last redoubt in the area on Friday, and welcomed a White House reversal of U.S. President Donald Trump's decision to pull out all U.S. troops.
With Washington's allies poised for victory against Islamic State fighters who are making a final stand in a pocket near the Iraqi border, the White House announced plans on Thursday to keep "a small peacekeeping force" in Syria.
The announcement partially reversed Trump's abrupt decision in December to withdraw the entire 2,000-strong U.S. contingent, which had alarmed Washington's Kurdish allies and prompted Defense Secretary Jim Mattis to quit.
An administration official on Friday put the total number of troops to stay at 400, split between a safe zone being negotiated for northeastern Syria and a U.S. military base at Tanf, near the border with Iraq and Jordan.
Although the U.S. contingent would now be small, the official indicated that the 200 troops in the northeast would be part of a wider commitment of about 800 to 1,500 troops also drawn from European allies to set up and observe a safe zone.
