http://news.bbc.co.uk/2/hi/middle_east/5393828.stmAl-Qaeda's number two has called US President George W Bush a "liar" who has failed in his war against the network, al-Jazeera TV channel says.Ayman al-Zawahiri is said to have made the remarks in a video on the internet.
It comes after a video released for the anniversary of 9/11, in which Zawahiri said Western forces were doomed to defeat in Iraq and Afghanistan.
The Egyptian militant is seen as the group ideologue. He has eluded capture despite a $25m bounty on his head.
"Bush you are a lying failure and a charlatan," Zawahiri was quoted as saying by Reuters news agency.
"We have gained more strength and we are more insistent on martyrdom," he said.
"Bush, oh failure and liar, why don't you be courageous for once and confront your people and tell them the truth about your losses in Iraq and Afghanistan," he said, according to the agency.
