BAGHDAD, Iraq (CNN) — A triple bomb attack in a northeast Baghdad neighborhood killed 28 people and wounded 68 others on Monday, Iraq’s Interior Ministry said.

It was the deadliest attack in the capital city in almost four months.

First, a bomb inside a parked car exploded in a marketplace in the Kasrah section of the Adhamiya neighborhood, a ministry official said.

Soon after, a second car bomb went off. When a crowd gathered around the exploded cars, a bomber wearing an explosives-laden vest detonated in their midst, the official said.

The attacks occurred about 8 a.m. local time.

Adhamiya is a Sunni neighborhood, but the Kasrah district is predominantly populated by Shiites. As such, the area is controlled by Iraqi security forces and not an Awakening Council.

Awakening councils are mainly made up of former Sunni insurgents who turned against al Qaeda and are credited for being one of the main factors that helped reduce violence in the country.

Among the victims of the Monday morning attack were two police officers, four Iraqi soldiers, five women and a number of students, the ministry official said.

Several soldiers and police personnel were also wounded in the blasts.

On June 17, 63 people were killed and 71 others wounded in a truck bombing in the Hurriya district in northwest Baghdad.

A day earlier insurgents bombed an outdoor market in the Iraqi town of Khalis in an attempt to kill the mayor, who was wounded in the attack along with the town’s deputy police chief, officials said.

Two others were killed when the explosive — hidden under a pile of trash — detonated near a health clinic, the official said.

Khalis Mayor Auday al-Khadran and the deputy police chief, Nihad Al-louaibi, were touring the market and were among the 13 wounded, the official said.

Khalis is in Diyala province, about 80 kilometers (50 miles) north of Baghdad, where al Qaeda in Iraq has a strong presence.
