IED attacks kill four US soldiers in Afghanistan

Four US soldiers have been killed in two separate bomb attacks in eastern Afghanistan, Nato said.

In a press release, Nato said home-made bombs, one of the main weapons of the Taliban, were used in both the attacks.

The attacks come a day after seven US soldiers were killed in two bomb attacks in southern Afghanistan.

The BBC's Ian Pannell says they follow a pattern of a fairly grim weekend for US forces in Afghanistan
