Filipinos take to river to cool off during heatwave

Filipinos head down to a river in Bulacan province to cool off during a heat wave descending on their cities.

In Manila, the heat index was forecast to hit the "extreme caution" level of 40C, when heat cramps and exhaustion are possible. The months of March, April and May are typically the hottest and driest in the archipelago nation, but conditions this year have been exacerbated by the El Nino weather phenomenon.
