Arab television station al Jazeera aired a new audio tape on Thursday said to be from Al Qaida leader Osama Bin Laden.
Following is a chronology of major statements attributed to Osama Bin Laden or his deputy Ayman Al Zawahri in the past year. At least 30 messages have been broadcast since Al Jazeera aired the first statement by Bin Laden in September 2001.
February 10 - Al Jazeera broadcasts audiotape attributed to Zawahri in which he says Iraqi elections held under foreign occupation are a sham.
February 20 - Al Jazeera broadcasts videotape in which Zawahri says governments cannot stop Al Qaida attacks, and the security of the West depends on respect for Islam and an end to aggression against Muslims.
June 17 - Al Jazeera broadcasts videotape in which Zawahri says reform and the expulsion of "invaders" from Muslim states cannot happen peacefully. He says any reform must be based on Islamic law and Muslim states should be free to govern themselves without interference or the presence of foreign troops.
August 4 - Zawahri warns Britons of more attacks, in the first video to focus on Britain's policies. He also tells Britain and the United States they will not have peace until they pull their troops out of Iraq and other Muslim states.
September 19 - Zawahri says in a videotape aired on Al Jazeera that Al Qaida carried out the July 7 suicide bombings in London to strike at "British arrogance". He denounces Britain for "the historical crime of setting up Israel and the continuing crimes in Afghanistan and Iraq".
October 23 - Zawahri urges Muslims in a video broadcast on Al Jazeera to help Pakistan's earthquake victims even though its government is an "agent" of the United States. He also denounces Pakistani President Pervez Musharraf.
December 24 - Zawahri praises the Taliban in an audio tape aired by Al Arabiya television, saying the Islamic movement still controls large parts of Afghanistan.
January 6 - Zawahri says in a video aired that President George W. Bush's plans to withdraw troops from Iraq meant Washington had been defeated by the Muslims. He also criticised Islamist groups, for believing in Western-style democracy and taking part in elections.
January 19 - Bin Laden warns that Al Qaida is preparing new attacks inside the United States, but says the group is open to a conditional truce with Americans, according to an audio tape attributed to him and aired by Al Jazeera.
