Obama signs big Pakistan aid bill
US President Barack Obama has signed into law a $7.5bn aid package for Pakistan, after fears it might impinge on Pakistani sovereignty were eased.
It follows meetings between the bill's authors, Democrats John Kerry and Howard Berman, and Pakistani Foreign Minister Shah Mehmood Qureshi.
The two congressmen issued a statement saying the bill set no conditions that would infringe Pakistan's sovereignty.
It triples non-military US aid to an annual outlay of $1.5bn for five years.
