A low-pressure area caused torrential rains and severe flooding in southern Philippines.

Drone video taken on March 7 shows the city of Iligan in Lanao del Norte province swamped by muddy floodwater.

At least 1,166 families in the city were affected by the deluge, the national disaster council said.

Swollen rivers halted traffic as water swamped the Tubod Bridge in a knee-deep flood. The downpour had also damaged the steel bailey bridge in Merila town when the soil supporting its approach had collapsed and left the structure askew. It has since been closed for repairs.

Iligan City Hall spokesperson Jose Pantoja said: 'It rained hard for hours until 3pm on March 6, then it started raining again. By then, the rivers were already swelling.'

Iligan City Mayor Celso Regencia has suspended work and classes at all levels while the city recovers. No casualties have been reported so far.
