Heavy rains and flooding have killed hundreds of people and displaced hundreds of thousands in Pakistan, India and Thailand.

Pakistan has been hit hardest, with monsoon rain crippling the country’s largest city, Karachi, and anger and frustration growing over the unpopular government’s slow pace of relief. About 900 villages have been submerged in the waters, and some 100,000 homes have been utterly destroyed.

At the heart of the flooding is southern Sindh province, the province that also was badly hit in the 2010 floods. Rains in 2010 left approximately one-fifth of Pakistan’s total land area under water.
