America's top soldier says hundreds of Iraqis, including some suspected resistance leaders, have been arrested following the capture of Saddam Hussein. The chairman of the US Joint Chiefs of Staff, General Richard Myers also said Saddam was not cooperating with US authorities who have been interrogating him since he was caught on 13 December near his hometown of Tikrit. Myers told the TV programme Fox News Sunday: "We've put our best interrogators on him. The only word I have is that he is not being cooperative." US troops have been cracking down on anti-occupation fighters in the week since Saddam was captured, although top officials have warned violence was expected to continue. **Iraqi Fighters Blow Up Oil Pipeline*** An oil pumping station in northern Iraq and pipelines carrying crude to refineries have come under attack, exacerbating the fuel shortage facing ordinary Iraqis. Unidentified attackers fired mortar shells on Sunday night at the pumping station 25km west of the oil-rich city of Kirkuk which feeds the internal and export pipeline network to Turkey and Syria, said Abd al-Karim al-Juburi, a security official. Iraqi police also said they arrested four Iraqis who planned to launch a rocket attack against US occupation forces based at Kirkuk airport and to blow up a giant fuel reservoir near Iraq's largest refinery at Baiji, 180km north of Baghdad. A US military spokeswoman in Baghdad said she had no information on the Kirkuk incident. Earlier, the US military denied reports of an attack on a pipeline between Baiji and Tikrit, hometown of captured ousted leader Saddam Hussein, and said the fires raging there were the result of burning "residual fuel". Three anti-tank rockets hit a pipeline south of Baghdad on Friday night causing a "significant" leakage, according to Asam Jihad, spokesman for Iraq's interim oil minister Ibrahim Bahr al-Ulum. Jihad also said that an explosive device hit a pipeline in the Mashahda region, 50km north of the capital. Also, US soldiers searching for a local shaikh suspected of organising anti-occupation attacks killed one Iraqi and wounded another after battling 25 allegedly armed men, said an army spokeswoman on Sunday in Tikrit. The resistance continued on Sunday when a rocket-propelled grenade (RPG) missed an American convoy and injured an Iraqi civilian in the northern Iraqi city of Mosul, said the US military. Elsewhere, in Ramadi a US patrol emerged unscathed after being hit by RPGs and small arms fire on Saturday, said the US military. In the same area, US soldiers shot at a car that sped past a checkpoint, injuring one of its occupants and detaining three, a statement said. **PHOTO CAPTION*** US soldiers walk past grafitti reading 'Long live Saddam, the fedayeen and the Mujahedeen' as they search a house in Tikrit, north of Baghdad.
