A fresh deluge has forced more evacuations along fast-rising rivers in the Filipino capital as the city and surrounding areas struggled to deal with widespread flooding triggered by nearly two weeks of rain.
Even though the weather was gradually improving, the number of displaced people was still rising, to nearly 300,000 in 500 evacuation centres.
Rescuers on rubber boats floated down flooded streets to reach thousands of residents marooned in submerged houses along the hardest-hit Maritkina River.
A fresh downpour pounded Manila, feeding the already-saturated waterways that flow into the network of rivers criss-crossing the coastal city of 12 million people.

Government forecasters said the weather would continue to improve throughout the day.
At least 23 people have died since Sunday, including nine in a landslide in a hillside slum in Quezon City and several others who drowned in outlying provinces.
