Najaf, Iraq ? U.S. forces ceded control of southern Najaf province to Iraqi police and soldiers, who marked the occasion Wednesday with a parade and martial arts demonstrations. But doubts remain about whether the Iraqis, vulnerable to insurgent attacks and militia infiltration, can handle security in more volatile provinces anytime soon.

In one of those provinces, Baghdad, police found 76 bodies, some of them blindfolded and handcuffed, on Wednesday. Many of the victims had been shot and some showed signs of torture, a police officer said on condition of anonymity for safety reasons. Two suicide car bombings also killed at least 19 people in the capital.

Home to 930,000 people, Najaf saw heavy fighting two years ago, but has been relatively peaceful lately. It was the third of Iraq’s 18 provinces to come under local control. British troops handed over southern Muthana province in July, and the Italian military transferred neighboring Dhi Qar in September.

Authorities in Najaf city banned vehicles as provincial and tribal leaders and dignitaries gathered in the dusty, blue bleachers of a soccer stadium for the handover ceremony.

About 1,500 police officers, soldiers and security personnel staged a parade around an infield of stubby brown grass, in festivities complete with warriors on horseback.

At one point, a small group of soldiers stepped forward with a live rabbit and tore it to pieces. The leader bit out the heart with a yell, then passed around the blood-soaked remains to his comrades, each of whom took a bite. The group also bit the heads off frogs, as some of those in the crowd held their noses from the stench.

Chewing on live animals is a traditional display of ferocity for elite troops in Iraq and was also observed by special units during Saddam Hussein’s rule.

Police then steered shiny new cruisers and motorcycles with ribbons and flowers stuck to their windshields around a track ringing the soccer field, which was still littered with fur and discarded frog legs.

“Our soldiers do a lot of things, but I’ve never seen them do anything like that,” said Maj. Gen. Kurt Cichowski, who attended the ceremony.

U.S. forces closed their major outpost in the region in September, as the 8th Iraqi Army Division and 6,900 police officers assumed greater responsibility in the province.

American forces will remain on standby in the area in case violence erupts again.

“Every province is important,” Cichowski said. “There’s 15 to go and we hope we can accomplish that by the end of 2007.”
