Pakistan's government has appealed for international help to tackle a flooding emergency that has killed more than 1,000 people and threatens to leave a third of the country - an area roughly the size of Britain - underwater.

Foreign minister Bilawal Bhutto-Zardari said on Sunday night that floods brought on by weeks of extreme monsoonal rainfall and melting glaciers would worsen Pakistan's already dire economic situation and that financial aid was needed.
