BAGHDAD -- Iraq's new parliament convened for the first time Tuesday amid intense pressure to quickly choose a new prime minster who can confront a militant blitz that threatens to tear country apart and a spike in violence that made June the deadliest month of the year.
The country's top Shiite cleric, Grand Ayatollah Ali al-Sistani, urged lawmakers last week to agree on a prime minister, president and parliament speaker before Tuesday's meeting in hopes of averting months of wrangling that could further destabilize the country. But the prospects of a quick compromise appear distant, and embattled incumbent Prime Minister Nouri al-Maliki - whose bloc won the most seats in April elections - has shown little willingness to step aside.
More than 250 of the legislature's 328 members were in attendance for Tuesday's session at parliament, which is located in the heavily guarded Green Zone in central Baghdad. The proceedings opened with the playing of Iraq's national anthem, and lawmakers then took the oath of office.
But the recent offensive spearheaded by the Islamic State of Iraq and Syria (ISIS), an al Qaeda breakaway group that has overrun much of northern and western Iraq, loomed over the lawmakers' meeting.
"There are many issues that need to be discussed today, but I believe that the most important one is to restore security and stability to Iraq, which is an essential condition for reform and development," said Mahdi al-Hafidh, who as the legislature's oldest member chaired the session.
"The main problem that Iraq faces is how to prepare the suitable atmosphere to practice democracy to fight sectarianism by respecting all sects," al-Hafidh said, before announcing a break to give lawmakers time to meet.
But CBS News correspondent Charlie D'Agata reports that the crucial process to create a new government then hit a brick wall; The first session of parliament had to be called off for the day after most Sunni and Kurdish lawmakers failed to turn up after the short break.
The threat posed to Iraq by the recent militant offensive was underlined by new casualty figures released Tuesday by the United Nations that put June's death toll at 2,417 - making it the deadliest month so far this year.
The figures issued by the U.N. mission to Iraq include 1,531 civilians and 886 security forces. UNAMI added that 2,287 Iraqis, including 1,763 civilians, were wounded.
As the violence escalates, U.S. officials said Monday that President Obama was sending an additional 300 troops to Iraq to help ensure security at the U.S. Embassy in Baghdad and surrounding areas, bringing the total of U.S. troops in the country to around 800.
The figures exclude deaths in embattled Anbar province, which is largely controlled by Sunni militants.
The second deadliest month this year was May, with 799 Iraqis killed, including 603 civilians. April's death toll was 750.
The latest casualty figures exceed even last year's peak. The U.N. reported that last July at least 1,057 Iraqis were killed and another 2,326 were wounded.
"The staggering number of civilian casualties in one month points to the urgent need for all to ensure that civilians are protected," the U.N. Special Representative in Iraq, Nickolay Mladenov, said in the statement.
Mladenov called on Iraqi political rivals to "work together to foil attempts to destroy the social fabric of Iraqi society."
