Days before the first anniversary of the US commando raid in Pakistan that killed Osama Bin Laden, President Barack Obama has used that success to launch a political strike on his main Republican challenger Mitt Romney.

In a pro-Obama commercial featuring Bill Clinton, the former US president alleges that Romney would have failed at killing Bin Laden.

John McCain, a prominent Republican senator, said Obama is touting the operation to boost political support.

“President Obama is shamelessly turning the one decision he got right into a pathetic political act of self-congratulation," McCain said.
