ROUGH CUT (NO REPORTER NARRATION)<br/> <br />STORY: Hundreds of activists belonging to various Islamist parties demonstrated in the Pakistani capital Tuesday to protest against the government's decision to hold a parliamentary review of fraught ties with the United States.<br/> <br />The protest came hours after U.S. President Barack Obama met Pakistani Prime Minister Yusuf Raza Gilani on the sidelines of a nuclear security summit in Seoul.<br/> <br />In the highest-level contact between the uneasy allies since U.S. commandos killed al Qaeda leader Osama bin Laden in a Pakistani military town last May, Obama conceded relations had been strained in recent months.<br/> <br />Islamabad called the commando raid a violation of its sovereignty, deeply straining ties between the two nations, which sank even further in November when NATO forces in Afghanistan killed 24 Pakistani border soldiers by mistake.<br/> <br />Pakistan shut off ground supply lines to the U.S.-led NATO mission in land-locked Afghanistan in the wake of the attack, and forced U.S. personnel off a base used to launch drone strikes against militants along the Pakistan-Afghan border.
