A man wearing a belt packed with explosives killed at least 26 Iraqi soldiers and wounded 26 others on Wednesday when he blew himself up inside a restaurant on an Iraqi army base north of Baghdad, army officials said.
Meanwhile, Iraqi troops, backed by U.S. forces, freed an Australian hostage after more than a month in captivity, officials said Wednesday.
There were no details available on the operation in Baghdad that led to the release of Douglas Wood, a 64-year-old engineer and resident of California, who was abducted in late April by a militant group calling itself the Shura Council of the Mujahedeen of Iraq.
In another suicide attack Wednesday, a car bomber slammed into two police cars on patrol in eastern Baghdad, killing eight police officers. The attack occurred in Baghdad's Zafaraniya neighborhood, according to police Lt. Thaer Mohamoud and 1st Sgt. Mohhamed Fadhil.
The lunchtime army base explosion took place in Khalis, about 12 miles northwest of Baqouba, Iraqi army Col. Saleh al-Obeidi said. Baqouba is 35 miles northeast of Baghdad.
Al-Obeidi said the man was wearing an army uniform and waited until soldiers had gathered for lunch before blowing himself up. The soldiers belonged to the Al-Salam battalion of the 2nd brigade of the Iraqi army in Diyala province.
