An Arabic-language magazine quotes a senior member of Al Qaida as raising the possibility that the group might poison US water supplies.
The Saudi-owned "Al-Majalla" weekly also reports in its latest edition that Al Qaida militants are in the ranks of Saddam Hussein loyalists who are attacking US-led forces in Iraq.
The reports are based on e-mail correspondence that Al-Majalla conducted with Abu Mohammed al-Ablaj, whom the magazine identified as a senior member of Al Qaida.
"It is something that would have to be viewed seriously," said a US counterterrorism official in Washington, speaking on the condition of anonymity.
The London-based Al-Majalla began receiving al-Ablaj's e-mails earlier this month, and a US counterterrorism official said previously that al-Ablaj was believed to be an Al Qaida operative.
In the earlier exchange with the magazine, al-Ablaj said Al Qaida was going to carry out major attacks in Saudi Arabia. Al-Majalla published the warning on May 11th -- a day before homicide bombers detonated explosives at three housing complexes in Riyadh, killing 25 people.
In the latest exchange of e-mails, al-Ablaj was quoted by the magazine as saying that Al Qaida did not rule out "the use of Sarin gas and the poisoning of drinking water in American and Western cities." He was quoted as saying Al Qaida "will present the Americans with their capabilities."
Sarin gas, a nerve agent, was used in a 1995 attack that killed 12 people on Tokyo's subways.
Even if terrorists managed to introduce Sarin into water supplies, dilution, purification systems and natural breakdown of the agent in the environment would make it very difficult, if not impossible, to deliver a lethal dose through a metropolitan water supply system.
Al-Ablaj also was quoted by the magazine as threatening to launch "smashing strikes against Israelis abroad."
