WASHINGTON — European and Asian markets today didn't think much of the lengthy action plan world leaders came up with over the weekend to address a sagging global economy.

The plan was produced at a weekend meeting of leaders of the Group of 20, which included the world's wealthiest countries such as the United States, Japan, Germany, Britain and France plus emerging powers such as China, Russia, Brazil and India.

But analysts say it will take more than one meeting to turn the tide for a global economy undergoing its worst upheavals in decades.

European stock markets traded modestly lower Monday following a mixed performance in Asia.

The G-20 nations agreed to hold another leaders' meeting before April 30, a little more than three months after President-elect Barack Obama takes office.

BAGHDAD — Iraqi lawmakers today began debate over a pact with the United States that will allow U.S. forces to remain for three more years, while an Iranian official close to that country's leadership praised the Iraqi Cabinet for approving the deal.The comments from Iran's judiciary chief marked the first time that the deal has met with clear-cut approval in neighboring Iran. Meanwhile, Syria, target of a deadly cross-border raid by U.S. forces in recent weeks, criticized the deal as virtual surrender to America.More than two-thirds of the 275-seat legislature attended today's session, raising confidence that parliament will be able to muster a quorum for the Nov. 24 vote. The session ended after the agreement's text was read to lawmakers, the first step to adopt legislation.Lawmakers are expected to meet again on Tuesday.The cabinet approved the pact Sunday, meaning the political parties in Prime Minister Nouri al-Maliki's coalition government are expected to have similar success in securing parliamentary support. If parliament approves, President Jalal Talabani and his two deputies must ratify it.Under the agreement, U.S. forces must vacate Iraqi cities by June, leave Iraq by the end of 2011 and grant Iraqi authorities extensive power over the operations and movements of American forces. It also prohibits the U.S. from using Iraqi territory to attack Iraq's neighbors, like Syria and Iran.

DUBAI, United Arab Emirates — Somali pirates hijacked a supertanker off the Kenyan coast, seizing the Saudi-owned ship loaded with crude and its 25-member crew, the U.S. Navy said Monday.Lt.

Nathan Christensen, a spokesman for the U.S. Navy's 5th Fleet, said the Sirius Star was carrying crude at the time of hijacking, but he did know how much.He also had no details about where the ship was sailing from and where it was headed.
