A suicide bomber detonated an explosives-rigged vehicle at a checkpoint near Baghdad on Wednesday, killing at least four people, security and medical officials said.

The bombing at a checkpoint leading to the Husseiniyah area, northeast of the capital, also wounded 21 people, the officials said.

The blast is the latest in a series of deadly attacks carried out by Takfiri ISIL group in and around Baghdad, including a bombing in a crowded shopping district on July 3 that killed 292 people, one of the deadliest ever to hit Iraq.

A few days later, Takfiris attacked a shrine in Balad, north of Baghdad, killing 40 people, and on Tuesday, a suicide bomber struck a market near the capital, killing at least seven people.

ISIL overran large areas north and west of Baghdad in 2014, but has since lost significant ground to Iraqi forces backed volunteer forces.
