The world must help Pakistan rebuild homes and livelihoods destroyed by devastating floods to secure hearts and minds in the militant-hit nation, the UNDP's regional head told a foreign news agency. Global cash pledges have been slow coming to bolster rescue and relief efforts ongoing in the flood-damaged nuclear nation, where more than 21 million people have been affected by a month of monsoon-triggered floods. Now helping Pakistanis rebuild homes and businesses, reduced to rubble by the unprecedented deluge, will be even more important to long-term regional and global stability, said UN Assistant Secretary General Ajay Chhibber.
