BAGHDAD -- Militants unleashed a wave of attacks targeting commercial areas in and around Baghdad on Monday, killing at least 24 people, officials said as Iraqi troops poised to recapture the Islamic State-held city of Fallujah, west of Iraq's capital.
No one immediately claimed responsibility for the attacks, which bore the hallmarks of the extremist Islamic State, which has been behind recent deadly attacks in Baghdad and beyond. Such attacks are seen as an attempt by the militants to distract the security forces' attention away from the front lines.
The deadliest of Monday's attacks took place in the northern, Shiite-dominated Shaab neighborhood of Baghdad where a suicide bomber rammed his explosives-laden car into a checkpoint next to a commercial area, killing five civilians and three soldiers.
The explosion also wounded up to 14 people, a police officer said.
A suicide car bomber struck an outdoor market in the town of Tarmiyah, about 50 kilometers (31 miles) north of Baghdad, killing four civilians and two policemen, another police officer said, adding that 19 people were wounded in that bombing.
And in Baghdad's eastern Shiite Sadr City district, a bomb motorcycle went off at a market, killing three and wounding 10, police said. Medical officials confirmed casualty figures. All officials spoke on condition of anonymity as they were not authorized to release information.
The attacks came amid a key Iraqi military operation to dislodge Islamic State in Iraq and Syria militants and retake Fallujah, which has been in ISIS hands for over two years. The operation was launched a week ago, with Iraqi forces teaming up with paramilitary troops and backed by aerial support from the U.S.-led coalition.
The city is one of the last major IS strongholds in western Iraq. The extremist group still controls territory in the country's north and west, as well as Mosul, Iraq's second largest city.
On Sunday, Iraqi Maj. Dhia Thamir said troops have recaptured 80 percent of the territory around Fallujah since the operation began and are currently battling IS to the northeast as they seek to tighten the siege ahead of a planned final push into the city center.
In a televised speech Sunday to parliament, Iraqi Prime Minister Haider al-Abadi called on Fallujah residents to either leave the city or stay indoors. Government officials and aid groups estimate that more than 50,000 people remain inside the center of the Sunni majority city.
