BAGHDAD, Iraq – American aircraft bombed a building where suspected insurgents were hiding north of Baghdad, killing seven people and wounding four, Iraqi police said yesterday.

The bombing took place late Monday in Beiji, site of Iraq’s largest oil refinery, Iraqi police Captain Arkan Jassim, who reported the casualty figures, said.

The American military did not comment on the deaths. It said only that an unmanned aircraft spotted three men planting a roadside bomb in the city 155 miles north of Baghdad, and that Navy F-14s bombed a nearby building the three had entered.

The Beiji refinery stopped production December 18 because tanker truck drivers refused to make deliveries across dangerous desert roads. Iraqi officials said Monday that the refinery resumed supplying Baghdad and other cities after taking security precautions for drivers.

In northeastern Baghdad, the sister of Iraq’s interior minister, Bayan Jabr, was kidnapped yesterday by gunmen who killed one of her bodyguards and seriously wounded another, the commander of the Interior Ministry’s special forces, Adnan Thabet, said.

He did not provide any other details about the kidnapping or the minister’s sister – including her name or age.

Mr. Jabr is a member of the Supreme Council of the Islamic Revolution in Iraq – the country’s largest Shiite party, also known as SCIRI. He was formerly a senior official of a militia that belongs to SCIRI, the Badr Brigade. Mr. Jabr has in recent weeks been the focus of criticism over allegations of torture and abuse at Interior Ministry prisons.

Also yesterday, the nephew of the commander of the Baghdad rescue police, Major General Ali Al-Yasiri, was kidnapped.

In other violence, eight people were killed yesterday in three attacks in Baghdad.

Gunmen attacked a car carrying construction workers in a western neighborhood, killing three, police Captain Qasim Hussein said. Another car carrying civilians was fired on in the same area, killing two people, said police 1st Lieutenant Thair Mahmoud. Three civilians elsewhere in Baghdad were shot to death, police said.

Meanwhile, an international team began reviewing the hundreds of complaints filed over Iraq’s parliamentary elections, and an Iraqi elections official said yesterday that results might not be ready for two more weeks.

The Independent Electoral Commission of Iraq has completed its investigation of almost 2,000 election complaints and will announce the findings Wednesday, a commission member, Hussein Hindawi, told the Associated Press.

But the commission won’t announce final election results until an international team finishes its work, meaning they might not be ready for two weeks, another commission member, Safwat Rashid, said. Officials previously said final results of the December 15 vote would be announced in early January.

The commission investigated 1,980 complaints, including 50 that were considered serious enough to alter results in some districts, an election official said.

The international team, which began its work Monday, agreed to review Iraq’s elections after protests by Sunni Arab and secular Shiite groups that the polls were tainted with fraud.

Preliminary results give the governing Shiite religious bloc, the United Iraqi Alliance, a big lead, but one that would still require forming a coalition with other groups.

Members of the International Mission for Iraqi Elections were in Baghdad to investigate fraud complaints, verify vote counts and review the decision by Iraq’s election commission to remove 90 people from Saddam Hussein’s outlawed Baath party from the tickets of political parties, Mr. Rashid said. It wasn’t known how many of the 2,000 complaints the team would investigate.
