Islamabad, Pakistan ? A masked militant, speaking in a video filmed in a mud hut, warns of new al-Qaida 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-Qaida claim of responsibility for the suicide attacks on foreign housing compounds in Riyadh, which killed 26 people and nine attackers, and bombings in Casablanca that killed 43 people and 12 attackers.

Obtained 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-Qaida; the remnants of the former Taliban regime; and the followers of Gulbuddin Hekmatyar, an Afghan rebel 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 spoke 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 organization. The official confirmed that the speaker on the tape was speaking for Hekmatyar’s party, which he said was working with al-Qaida and the Taliban.

The White House declined to comment on the video Saturday.

The speaker in the tape says al-Qaida 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 recent attacks in Riyadh and Morocco were planned and they were part of our martyrdom operations. You will see more such attacks in the future,” the speaker in the video said.

Saudi and U.S. officials have blamed al-Qaida for the Riyadh attacks. Moroccan authorities say an international terrorism ring carried out the Casablanca attacks, and they are looking at possible links to al-Qaida.

In this picture taken from television, an Arabic-speaking guerrilla who identified himself as Abu Haris Abdul Hakim, warns of new al-Qaida suicide attacks and says Osama bin Laden's terror network carried out deadly bombings in Saudi Arabia and Morocco.

At one point, the man holds up a crudely written sign that says June 14th, apparently a reference to the date it was made — though it was impossible to confirm.

“Oh our brothers in Palestine, Chechnya, Kashmir and Iraq: We will have good news for you very soon. And it will be about our supremacy over the Americans. This will be in the shape of martyrdom (suicide) attacks against Americans in the current month,” Hakim said.
