KUSAIYBAH, Iraq: US Marines race to secure a landing zone as a Blackhawk helicopter carrying top US commander in Iraq General George Casey arrives for a ceremony to restore Iraqi border security in the restive city of Kusaiba, Iraq, a recent battle ground during US operation Steel Curtain, along the Syrian Iraq border, 30 november, 2005. US President George W. Bush said in a speech Wednesday that US troop levels in Iraq would depend on conditions there, not on "artificial timetables set by politicians in Washington."
