A series of bomb blasts in and around Baghdad killed at least 15 people and wounded more than 20 on Saturday, according to media reports.

Eight of those people were in the commercial Bab al-Sharqi shopping district in central Baghdad, where three explosions were recorded.

Another two bombs killed construction workers travelling in a truck or minibus between Baghdad and Fallujah near the town of Abu Ghraib.

Dr. Omar Delli told Agence France Presse (AFP) that Fallujah Hospital received seven bodies and seven wounded from the truck attack.

It was a roadside bomb that went off near a pick-up carrying construction workers in Zobaa village west of Abu Ghraib, an unnamed health official, said according to Al Jazeera.

A witness in Bab al-Sharqi told AFP: Three bombs exploded one after the other. I saw a woman, who was serving tea to customers, lose a leg in one of the explosions.”

Although the pace of violence in Iraq has dropped in the past few years since hitting a peak in 2006-2007, militant insurgents seeking to destabilize the fragile government still conduct attacks regularly.

The sporadic violence raises fears of what the future will hold for Iraq once American troops finally withdraw from the country by the end of this year.

There are, however, tentative plans to keep a small US troop presence into next year.
