""Our military commanders will take whatever action is necessary to secure Fallujah on behalf of the Iraqi people," Bush said at the White House after meeting with Swedish Prime Minister Goeran Persson. ... US aircraft and helicopters for a second day blasted suspected insurgent positions with missile and machine gun fire as a heavy gunbattle reportedly broke out near the rail station in Fallujah, 50 kilometres (30 miles) west of Baghdad. ... Fighter jets and heavily armed AC-130 aircraft could be heard over Fallujah after several marine units, backed by tanks and mortar fire, came under fire from small arms and rocket-propelled grenades. While plumes of black smoke rose from several buildings hit in helicopter raids, US military spokesman Brigadier General Mark Kimmitt told BBC radio: "We are not deliberately targeting civilians nor carrying out retribution or punitive action."
