Chad: a moat around the capital.

The government [of Chad] is digging a 10-foot-deep trench around the capital, Ndjamena, to prevent a repeat of an attack last month, when rebels in pickup trucks rolled in and fought two days of heavy battles. The ditch will all but encicle the city, slicing through neighbourhoods and forcing vehicles to pass through fortified gateways, a security official said. The remaining trees that line the avenues of central Ndjamena are being felled. Residents say the rebels used trees knocked down by rocket-propelled grenades and cannon fire to block roads during the fighting.
