Deadliest year for US troops in Iraq

The U.S. military announced six new deaths Tuesday, making 2007 the bloodiest year for American troops in Iraq despite a recent decline in casualties and a sharp drop in roadside bombings that Washington links to Iran.

With nearly two months left in the year, the annual toll is now 853 — three more than the previous worst of 850 in 2004.

But the grim milestone comes as the Pentagon points toward other encouraging signs as well — growing security in Baghdad and other former militant strongholds that could help consolidate the gains against extremists.
