But they deny responsibility for the Riyadh bombing

More threats from Al-Qaeda, from [1] The Evening Standard:

One of the most senior figures in the al Qa'eda terror group has pledged that 2004 will be a year of attacks on America.

The comments appeared on an Islamist website and are believed to have come from Abdulaziz Issa Abdul-Mohsin al-Moqrin.

The website also carries a warning that Saudi Arabian rulers will be unable to prevent further attacks.

However, he also claims that al Qa'eda was not behind last week's suicide car bombing of a security building in the Saudi capital Riyadh.

Security officials believe that al-Moqrin is al-Qa'eda's leader in Saudi Arabia, with a major police operation currently attempting to capture him.

The Al Haramain Brigades, a Saudi militant group, have claimed responsibility for last week's Riyadh attack and said they were filling in for al Qaeda, which was preoccupied fighting "crusaders".
