A group calling itself al-Qaida in Iraq has ridiculed this week's terrorism conference in Spain marking the first anniversary of the bombing of Madrid trains that killed nearly 200 people and wounded more than 1000.

A message posted on a web site used by Islamists describes the international officials and experts who met in Madrid as 'infidels' who will never be victorious.

At the conference, which concluded Friday, U.N. Secretary-General Kofi Annan said the world must move quickly to prevent terrorists from getting access to nuclear weapons.

Spain observed five minutes of silence Friday to remember the March 11, 2004 coordinated bombings of four Madrid trains, which killed 191 people. 

Islamic militants, predominantly from Morocco and sympathetic to al-Qaida, claimed responsibility for setting the bombs.
