ISLAMABAD: A masked militant, speaking in a video filmed in a mud hut, warns of new al-Qaeda suicide attacks and says Osama bin Laden's terror network carried out deadly bombings in Saudi Arabia and Morocco.

If authentic, the video would be the first al-Qaeda claim of responsibility for the suicide attacks on foreign housing compounds in Riyadh, and bombings in Casablanca.

Obtained on Saturday by The Associated Press, the video also appeared to reflect an increasing alliance between three top opponents of the United States in Afghanistan: Al-Qaeda; the remnants of the former Taliban regime; and the followers of Gulbuddin Hekmatyar, an Afghan militant leader whom the United States calls a terrorist and has tried to kill.

The man on the scratchy videocassette, who identified himself as Abu Haris Abdul Hakim, said he speaks in the name of all three groups. He spoke in Arabic, but did not give his nationality. His face was covered by a black turban.

The videotape was obtained from a senior intelligence official in Hekmatyar's Hezb-e-Islami organisation. The official confirmed that the speaker on the tape was speaking for Hekmatyar's party, which he said was working with al-Qaeda and the Taliban.

The speaker in the video says al-Qaeda is active and planning new attacks this month, saying, "Osama is alive and in Afghanistan." Though he suggests the attacks will take place in Afghanistan, he also points to wider operations.

The speaker said the coming attacks would mimic those carried out in the Afghan cities and towns of Kabul, Kandahar and Spinboldak. "Our Mujahideen brothers are regrouping in Kunar, Khost, Gardez, Jalalabad, Kabul and Logar," he said, referring to parts of Afghanistan. "They are engaged in preparations for the attack."

In the 35-minute video, the speaker is seen seated on a straw mat on the floor of a brick mud hut with a Kalashnikov assault rifle by his side as he read from several sheets of paper. With his face hidden, it was impossible to confirm his identity, though the intelligence official also said it was Hakim.
