As Iraqis welcomed the Islamic New Year Thursday, insurgents marked the occasion with more attacks. And the charred bodies of more than 20 Iraqi truck drivers and security forces were discovered south of Baghdad.

Police say the truck drivers had been transporting sugar for the trade ministry when they were ambushed in an area known as the "triangle of death." Two policemen and two soldiers escorting the convoy were also killed. Police said they believe the attack occurred at least two days ago. However, interior ministry officials cautioned that they could not confirm the attack or the casualties.

Meanwhile, at least five other Iraqis were killed in attacks Thursday in Baghdad, Kirkuk and Baquba.

And the government announced it will close its borders for five days starting next Thursday as a precaution against attacks during the Shi'ite religious observance of Ashura. Last year, more than 170 pilgrims were killed in suicide bombings in Baghdad and Karbala during the solemn religious rite.
