New warnings have been issued in Pakistan as floods spread in the southern province of Sindh.

Rising waters there have forced many thousands of people to flee, adding to the millions already needing emergency assistance.

After broaching some of its embankments, the Indus river is now as wide as 28km in some places.

The Indus, for so long a lifeline for many Pakistanis is now central to the country's problems.
