In the central Philippines, efforts to rescue victims from Monday’s 6.7-magnitude earthquake in western provinces are being hampered by impassable roads and bridges. There are at least 15 confirmed dead.

The worst-hit area is the island province of Negros where at least one landslide in a mountainside town near the epicenter is believed to have buried dozens of people alive. The Philippine Civil Defense Office says all major roads and bridges to that area are badly damaged and difficult to pass.
