Slow response to Pakistan floods 'could cost more lives'

Aid agencies warn that a slow response to Pakistan's floods could lead to even greater loss of life.

More than 300 people have been killed and over 7 million have been affected by heavy monsoon rains.

Many still do not have access to food, water, shelter or health care.

The Pakistan air force has begun dropping aid in the worst affected province, Sindh, as Orla Guerin reports.
