Pakistan navy in flood search effort
Pakistani military forces have been using boats and hovercraft for search and rescue missions on the floodwaters of Sindh province.
The navy says they will concentrate on relief only when the search effort comes to an end.
Three weeks after the start of devastating floods in Pakistan, waters are continuing to rise in the southern province of Sindh and parts of Punjab.
One-fifth of the country's land area has now been submerged.
