Iraqi police came under attack in Baghdad overnight in what US-led authorities have described as a growing pattern of Iraqi strikes and threats against compatriots cooperating with the occupying forces. Unidentified assailants lobbed grenades at the police station in northern Baghdad, injuring two Iraqi policemen; no US soldiers were wounded in the attack. At least two attackers threw three or more grenades and fired gunshots at the police station in the city's Ash-Shab district, where US military police are stationed to train members of Iraq 's new police force. Also, three U.S. soldiers were wounded in two separate blasts in central Iraq, with no sign of let-up in a guerrilla campaign against U.S. occupation forces. With the wave of attacks on US troops and those working with them showing no sign of a let up, the coalition announced Tuesday it will offer rewards starting at 2,500 dollars for information leading to the arrest of the attackers. "The minimum reward is 2,500 dollars and will be greater for more important information," the Arabic-language Al-Sabah said, providing two satellite telephone numbers for people to contact. **British Soldier Wounded in Basra*** With the security situation in and around Baghdad still distinctly fragile, a military officer in the southern city of Basra said a British soldier had been wounded on a joint patrol with Iraqi police officers at the weekend. A bullet struck the soldier in the leg as he and Iraqi police patrolled the northern edge of the port city Basra, Lieutenant Commander Clive Woodman said. **Tony Blair Faces New Grilling over Iraq War*** Meanwhile, Tony Blair faced some tough questioning from deputies on whether the war on Iraq was justified, a day after a parliamentary report rapped the manner in which he took Britain into the conflict. Blair was expected to face a sustained examination before the liaison committee -- made up of the chairmen of all the House of Commons' watchdog select committees -- after 9:00am. The premier regularly testifies before the liaison committee -- typically doing so in shirt-sleeves -- to field detailed questions on government policy and topical issues. With question marks hanging over the government's case for war because of the failure to find weapons of mass destruction in Iraq, the liaison committee was thought likely to query the quality of the intelligence which led Blair to claim that Saddam Hussein posed a real and immediate threat to British interests. Blair's grilling comes just 24 hours after parliament's foreign affairs committee produced a much-awaited report after investigating two dossiers published by the government in the run-up to war in March. **PHOTO CAPTION*** A US soldier frisks an Iraqi father while his son waits for his turn at a mobile checkpoint in Kadhamiya north of the capital Baghdad, Iraq on Monday July 7, 2003 (AP Photo/Wally Santana)
