Flash floods killed 109 people and some 700,000 have been affected, the Pakistan National Disaster Management Authority said on Sunday.
Military engineers repaired roads and bridges in the mountainous north to help rescuers reach people cut off for weeks. The river Indus, which flows down from the Himalayas to the Arabian Sea, flooded at several points in southern Sindh province.
More rain is expected.
Around 350,000 people have been evacuated from the banks of the Indus in past two days.
While weeks of heavy rain in Myanmar have left at least 47 people dead and damaged farmland.
More than 212,000 hectares of farmland in 12 out of 15 states and divisions across the country were seriously affected by floods as the heavy rain continues. Floods and landslides destroyed more than 20,000 homes and affected some 200,000 people in the Sagaing and Mandalay regions as well as in the Kachin and Shan states, local media reported.
The UN’s Office for the Co-ordination of Humanitarian Affairs (OCHA) has warned the death toll is expected to be rise.
