Pakistan's Prime Minister Yousuf Raza Gilani on Wednesday called for the world's help in fighting "terrorism and extremism" after the killing of al-Qaida leader Osama bin Laden near Islamabad.

"Security and the fight against extremism or terrorism is not the job of only one nation," Gilani told reporters in Paris, where he met with French business leaders.

At least 38 people were killed when Ethiopian armed men attacked a rival community in a remote border region of north Kenya, a local official said Wednesday, warning the toll could rise.

"Where the incident occurred is very remote and mostly not accessible," Rift Valley Provincial Commissioner Osman Warfa told Agence France Presse in an update on Tuesday's attack.

France fears it will be the target of reprisals for the killing by U.S. forces of al-Qaida leader Osama bin Laden, French Interior Minister Claude Gueant said on Wednesday.

"Threats are everywhere and we can indeed fear that France will, like the United States and other friendly countries, be the target of reprisals and desire for vengeance," Gueant said on RTL radio.

Al-Qaida chief Osama bin Laden was unarmed when he was shot dead by U.S. special forces, but he tried to resist and there was a "volatile firefight," the White House said Tuesday.

The revelation, likely to stoke anger in parts of the Muslim world, came from President Barack Obama's spokesman Jay Carney as he provided the most detailed account yet of the Sunday night raid in Abbottabad, Pakistan.

CIA Director Leon Panetta said in an interview Tuesday that officials ruled out informing Islamabad about a planned raid against Osama bin Laden's compound as they feared their Pakistani counterparts might alert the al-Qaida chief.

Panetta told Time magazine that "it was decided that any effort to work with the Pakistanis could jeopardize the mission: They might alert the targets."

Pakistan on Tuesday faced a violent backlash over Osama bin Laden's killing, fearing revenge attacks and struggling to fend off tough questions over how the a-Qaida mastermind escaped detection so long.

The daring helicopter raid by dozens of U.S. special forces -- who were operating independently on Pakistani soil -- ended a decade-long manhunt for the mastermind of the 9/11 attacks, but Islamabad was kept in the dark.

British police said Tuesday they had arrested five men under anti-terrorism legislation close to a nuclear plant in northwest England.

The men were stopped in a vehicle by officers near the Sellafield nuclear site in Cumbria at around 4:30 pm (1530 GMT) on Monday.

A freak tornado hit New Zealand's largest city Auckland on Tuesday, killing one person and injuring dozens more as it ripped the roof off a suburban shopping mall, Agence France Presse reported.

Packing winds of 200 kilometers an hour (125 miles an hour), the twister hit the suburb of Albany without warning at about 3pm (0300 GMT), flipping cars and uprooting trees as it carved a trail of destruction stretching for kilometers.

Up to 10 Afghan guards were killed Tuesday in a NATO air strike along a highway in southern Afghanistan, police said, in the latest friendly fire incident involving the alliance's forces.

The armed guards were escorting a supply convoy to NATO bases in southern Afghanistan when they were hit in the province of Ghazni, Mohammad Hussain Yaqoubi, the deputy provincial police chief told Agence France Presse.

The United States closed its embassy and three consulates in Pakistan on Tuesday, a day after Osama bin Laden was killed near the capital Islamabad, Agence France Presse.

"The U.S. embassy in Islamabad and the consulates in Peshawar, Lahore and Karachi are closed for routine business to the general public until further notice," the embassy said.
