Japanese police control a checkpoint near the edge of the "exclusion zone" that surrounds the nuclear plant.

But Greece may not sign on the dotted line until Israel has agreed with Lebanon and Cyprus on where a border is to be drawn in the sea, demarcating each country's economic exclusion zone.

This is felt most acutely in Fukushima's "exclusion zone", whose residents have been commanded to stay in their shelters-and where lorry-drivers are afraid or unable to reach them.
