The Al Qaeda leader, Osama bin Laden, has accused conservative Arab leaders of plotting with the West against Muslims. He has urged his followers to prepare for jihad, in a recording posted on Islamist websites.
The tape mentions Saudi Arabia and Egypt and contains a poem honouring Gaza's resistance to Israel's three-week offensive in December and January.
Osama bin Laden wants a list drawn up, warning Muslims about "enemies, hypocrites and their media".
He singled out the BBC and United States and Saudi funded Arabic-language television stations in Iraq and Saudi Arbia.
More than 60 messages have been broadcast by bin Laden, his second-in-command Ayman al-Zawahri and their allies since the 11 September attacks in New York in 2001.
