BAGHDAD, Iraq (CNN) -- The Iraqi government implemented new security measures and arrested 11 security officials a day after a string of bombings in Baghdad killed at least 100 people and wounded hundreds more, an interior ministry official told CNN on Thursday.
The measures, ordered by Prime Minister Nuri al-Maliki, include additional security checkpoints across the capital, more stringent vehicle searches and random security stops.
Iraqi state television also reported that the presidency of Iraq's parliament has called for an emergency session among the heads of parliamentary blocs and the parliamentary defense and security committee on Friday to discuss the security situation.
Iraqi lawmakers are on a one-month vacation.
Eleven high-ranking security officials from the Iraqi army and police were detained for investigation Thursday, said Brigadier General Qassim Atta, a spokesman for the Baghdad Operations Command.
"They are in charge of security in Salhiya and Bab Muadham, two areas of Baghdad targeted in the bombings," Atta said.
Thursday's events follow a late-night meeting that included al-Maliki and Iraq's defense, interior and national security ministers, along with senior representatives from the military and intelligence service.
The six bombings -- two targeting official buildings -- struck Iraq's capital within one hour Wednesday, killing at least 100 people and wounding more than 500.
At least two people were killed Thursday morning when a bicycle rigged with explosives exploded in the Hafdh al-Qadhi commercial area in central Baghdad.
In Babil province, south of Baghdad, at least four people were also killed and 76 were wounded Thursday in a string of bombings, an Iraqi Interior Ministry official said.
Wednesday's bombings marked the country's most fatal day since the United States pulled its combat troops from Iraqi cities and towns nearly two months ago and left security in the hands of the Iraqis.

* Al Qaeda blamed for Iraq violence wave
* Baghdad to remove blast walls around neighborhoods
In one attack, a truck bomb exploded outside the Ministry of Foreign Affairs. The blast blew through the front of the building, sending some vehicles flying and leaving others in mangled twists of metal in the area, which is just outside the restricted International Zone, also known as the Green Zone.
Another truck bomb went off outside the Ministry of Finance building and, in central Baghdad, a roadside bomb exploded on Kifa Street.
A bomb also exploded in the Salhiya neighborhood, where on Tuesday security forces had avoided injuries by successfully defusing a truck bomb.
Wednesday's other two bombs exploded in eastern Baghdad's Beirut Square, officials said.
Two people believed to be connected to the bombings have been arrested, an official with the Iraqi army told CNN on Wednesday.
The two suspects were driving in a car rigged with explosives when they were stopped by Iraqi security forces, the official said. The suspects were believed to be senior al Qaeda leaders, the official said.
The United States pulled its combat troops from Iraqi cities and towns on June 30, leaving security responsibilities to the Iraqis but remaining in a training and advisory capacity. The U.S. military continues to conduct combat operations in areas outside cities and towns.
Since then, al-Maliki has ordered his government to remove the concrete blast walls that line Baghdad's streets and surround whole neighborhoods.
The order does not cover the Green Zone, which houses Iraqi government buildings and the U.S. Embassy, military installations, government institutions, hotels and some private companies.
Following the bombings, the U.S. commander in charge of training Iraqi security forces said he was frustrated with how much remains to be done.
"Clearly, there was a lapse of security or this would not have happened." said Lt. Gen. Frank Helmick, commander of Multi-National Security Transition Command-Iraq, which is training Iraqi security forces.
He said he is experiencing "personal frustration with where we are today" regarding the training of Iraqi troops. Supporting Iraqi forces in the field is a challenge, he said, because many logistical and personnel issues plague the forces.
"It's very, very difficult, and it takes time," he said, "to build an intelligence, surveillance and reconnaissance technician, to build platforms for the Iraqis -- in other words, airplanes with qualified crews, Iraqi crews that can fly them and analyze the data."
U.S. forces will "really have to focus on and accelerate" the pace of training through next year, he told reporters at the Pentagon via video conference from Iraq.
