Polish troops received their first Iraqi resistance attack and Australian forces were told they are unlikely to return home soon, as sabotage, attacks and the voice of the still elusive Saddam Hussein continued to plague the US-led coalition three months after the war in Iraq was declared over. Five mortar bombs were fired at the Polish base in Hilla, near Baghdad, but all fell on the edge of the facility and caused no damage, a Polish defense ministry spokesman said. US forces failed to capture the assailants after giving chase. The attack was the first reported against Polish troops in Iraq, where some 300 military personnel are working to prepare for the deployment of a multinational division under Polish command. Australia for its part announced Friday that its troops, which took part in the US-led invasion of Iraq to topple Saddam's regime in March, were unlikely to return home in the near future. Defence Force chief Peter Cosgrove said the deployment would last "longer than months," and added "after all now, we're in a position of supporting the rehabilitation and reconstruction of Iraq. Australia contributed 2,000 troops to the war on Iraq but has since scaled back its deployment. Meanwhile saboteurs were blamed for an explosion in an oil pipeline near the refinery city of Baiji, some 200 kilometers (125 miles) north of Baghdad, causing a fire which was still raging Friday. Majid Mamuni, general director in charge of pipelines at the Baiji refinery, told AFP, "It was a crude oil pipeline going from Kirkuk to Baiji," adding, "I think it was sabotage." Only on Thursday the coalition had announced that Iraq's main northern pipeline which was severely damaged in a sabotage attack on June 12 would be back online within a few days. The key pipeline exports oil to Turkey's Mediterranean terminal of Ceyhan. Attacks on oil and gas installations are a setback to coalition efforts to revive the energy sector, which it hopes will provide needed funding for reconstruction efforts. In other acts of defiance, suspected former regime loyalists in the Fallujah area again clashed with US troops Friday, wounding an unknown number of soldiers in an apparent rocket-propelled grenade (RPG) attack on a convoy followed by a barrage of small arms fire, witnesses said. Two of the four Iraqi attackers were killed, they added, although a US military spokeswoman contacted by AFP said she was not aware of the incident. **News Saddam Tape*** A new audiotape attributed to Saddam Hussein, aired Friday, urges his followers continue the uprising against U.S. occupation forces and keep control of former state property to use in the rebellion. The voice said the tape was made Sunday. The news message was broadcast by the Qatar-based Al-Jazeera satellite television station. "The feeling of defeat and bitterness might lead some people to commit treason ... instead of being a gun pointed at the enemy," said the voice. "I ask people to keep the properties of the country and the party until the situation changes or to donate their value to the glorious resistance," the voice said. The voice stressed the need to battle. "Our faith is great that God will support us, and that one day the occupation army will falter and that victory is possible at any moment. We must not let things slip away and our situation become desperate," the voice said. "The balance has shifted, after the military confrontations and this has not changed. They (Americans) will not be able to stop this." "I say that this shift in balance has happened because of the great mujahedeen and faithful fighters who have worked and struggled to confront the occupation and throw the invaders outside Iraq so that Iraq can return to its normal state after that." **PHOTO CAPTION*** A US soldier mans his gun on top of an army vehicle in the flashpoint town of Fallujah.
