Iraq suicide bomb kills 17 at police forensics lab

The blast came a day after suicide bombers in vans and SUVs,  helped in at least two cases by gunmen with silenced weapons,  attacked three Baghdad hotels, killing 36 people.

Two of the hotels are used by western visitors and media and  the U.S. military commander said the attacks might be aimed at  deterring foreign companies, and preventing Iraq from securing  the investment it needs for future prosperity and stability.
