LONDON: British Prime Minister David Cameron is supporting Western alliances with Pakistan amid questions about how terrorist Osama bin Laden lived for so long there before he was hunted down and killed by US commandos.

In a news conference with President Barack Obama, Cameron said that allies must work with Pakistan more closely than ever, not turn away. He said Pakistan has suffered mightily in the fight against extremism.

“Their enemy is our enemy,” said Cameron.

Cameron said he and Obama are also committed to helping those fighting for freedom across the Arab world.

He said of Libyan ruler Muammar Qadhafi: “He must go.”

Britain and the United States are key players in a Nato campaign to halt Qadhafi’s violence against his people.
