Washington: The approval rating of US President Barack Obama has increased by 11 per cent since the killing of al Qaeda chief Osama bin Laden, according to a latest opinion poll.

A new CBS News/New York Times poll shows that 57 per cent of Americans generally approve of Obama in the wake of the raid deep inside Pakistan that killed Osama on Monday.

Two weeks ago his overall approval rating was at 46 per cent.

A whopping 85 per cent of those polled gave Obama high marks for his handling of the operation to find bin Laden, the poll said.

In a CBS News Poll conducted in December 2003, just after the US military captured Saddam Hussein in Iraq, the then President George W Bush received a 60 per cent approval rating -- a jump of about six percentage points.

But it was short-lived, and his poll numbers never reached that height again, CBS News said.

The poll also revealed that approval ratings for Obama's handling of the threat of terrorism, the war in Afghanistan, and foreign policy in general have increased in the wake of bin Laden's death.

A significant 72 per cent of Americans (including 53 per cent of Republicans) approve of Obama's handling of terrorism, his highest rating on the issue since taking office.

In last month's poll, only 39 per cent approved of Obama's handling of foreign policy -- his lowest rating to date. Now, 52 per cent say they approve, CBS said.

However, the polls reflect that the approval rating on Obama's economic policy has gone down.
