Australian Prime Minister John Howard, together with U.S. ambassador Robert McCallum, attended a ceremony at the U.S. embassy here Monday, which marks the fifth anniversary of the September 11 terrorist attacks on the United States in 2001.
Australian Foreign Minister Alexander Downer, Defense Minister Brendan Nelson and Opposition Leader Kim Beazley were also present at the ceremony.
The U.S. flag was lowered to half mast during the ceremony which also included a bagpipe rendition of Amazing Grace and a minute's silence to remember the nearly 3,000 victims in the attacks.
Howard reaffirmed Australia's commitment to fighting against terrorism and working with the United States.
"Terrorism is the enemy of all people of good wills," he said.
"It is the enemy of all of the great religions of the world. It is a blasphemy on Islam, to the name of Islam to be invoked to justify terrorism," he said.
