The World - Baghdad -

Baghdad - Bombs tore through two popular pet markets here Friday, killing 77 people, in Baghdad since a U.S. troop buildup reached its peak in July. The apparently coordinated attacks, occurring within 10 minutes of each other, were reminiscent of large-scale suicide bombings before the buildup and underscored what U.S. military officials have warned are the shifting tactics of insurgents. At least one woman with explosives strapped to her.Some Iraqi police officials said women carried the bombs at both markets.
