Persistent heatwave adds pressure to Japan earthquake rescue efforts

A persistent heatwave is adding pressure to rescue efforts, days after a 7.1 magnitude earthquake struck southwest Japan. The death toll has climbed to 34, and authorities cannot confirm the number of those still missing, even as time runs down on the critical 72-hour window for survival. Temperatures are expected to hit close to 40°C over the weekend, raising the risk of heatstroke. This, as tens of thousands of households are still without power and water. Japan's Met Agency has warned that seismic activity remains high, with the continued risk of major jolts over the next few days. Michiyo Ishida reports.
