On Wednesday, U.S. Secretary of State Hillary Clinton announced aid for flood-ravaged Pakistan and denounced a suicide bombing in a Peshawar market.
Pakistanis face life-threatening shortages after floods killed 1,500 people and left thousands missing and trapped without access to food or clean water.
The floods in northwest Pakistan, the worst in 80 years, have devastated the lives of more than three million people.
It's too early to gauge the economic cost of the floods but they are likely to be staggering.
Pakistan is heavily dependent on foreign aid and its civilian governments have a poor history of managing crises, leaving the powerful military to step in.
The floods, which started a week ago, are likely to spread as more rains are expected. A breakout of water-borne diseases such as cholera would pose new risks.
