Aftershocks rock Japan

Firefighters on the northern Japan island of Hokkaido battled to contain a blaze at an oil refinery sparked by last week’s earthquake, as powerful aftershocks continued to rumble through the region.

Under a plume of oily black smoke and huge pillars of flame, firefighters doused a storage tank with chemicals to try to extinguish the fire at the refinery in the Hokkaido town of Tomakomai.
