At least 16 people have been killed in a fresh spate of violence across Iraq

At least 16 people have been killed in a fresh spate of violence, including bomb attacks and a shooting incident, across Iraq.

Saturday’s wave of attacks began with the explosion of a roadside bomb in a commercial street in the northern city of Tikrit, which was followed by a car bomb that struck policemen inspecting the site minutes later.

According to Press TV, five policemen and two civilians were killed and 18 people were wounded in the bombings.

An explosive-laden car also blasted at a security checkpoint near the town of Adeim located about 100 kilometers (60 miles) north of the capital Baghdad, leaving three civilians and three cops dead.

At a military checkpoint near the northern city of Mosul, a roadside bomb killed two soldiers and injured three others.

The head of a local radio station, identified as Mohammed Bedwei, was also shot dead at a checkpoint in eastern Baghdad.

The killings come as Iraqi security forces supported by Sunni tribesmen are battling militants in the western province of Anbar.

The Iraqi government has stepped up efforts to boost security across the country over the past few months.
