NEW YORK - Al Qaeda's No. 2 leader has lashed out at Afghanistan's government and claimed that any U.S. gains in Iraq will be temporary.

In a new video, Ayman Al-Zawahri also lauded his group's fight in several countries and criticized leaders of those nations for their fight to counter the terrorists.

His comments are reported by the SITE Intelligence group.

Zawahri's comments, carried on a militant Web site, came about a week after his last message in which he accused President-elect Barack Obama of turning his back on his black heritage to gain power.

Osama bin Laden's top lieutenant didn't refer to the attacks in Mumbai, India, late Wednesday and early Thursday that killed or injured hundreds.

Intelligence analysts say the violence carried trademarks of al Qaeda but evidence has been pointing to homegrown terrorists.

A little known suspected Islamic militant group has claimed responsibility.

In Thursday's video, SITE says Zawahri labelled Afghan President Hamid Karzai's recent attempt to negotiate with Taliban insurgents a sign of his government's weakness.

He also accused the United States of giving phoney reports of success in the turbulent region, maintaining the Americans are doomed to fail in Afghanistan and the tribal areas of Pakistan.

Discussing Iraq, Zawahri said that U.S. gains are temporary.

He also stressed that Sunni Awakening Councils -- former insurgents who have revolted against al-Qaida -- will not be accepted by the Shiite majority government.

U.S.-based SITE said Zawahri defended against charges of al Qaeda's killing innocent civilians, calling the reports Western propaganda.
