A car bomb exploded in a business district of central Baghdad today, witnesses and Al-Arabiya television reported.
The blast sent a huge plume of black smoke up into the sky, but it was not immediately clear if there were any casualties.
The explosion occurred in al-Nasr Square, a main intersection of shops, offices and apartment buildings. The square is located near the Tigris River.
On Saturday, two car bombs exploded a few hundred yards from the site of today’s blast, hitting an American security company convoy and killing at least 22 people – including two Americans. That attack also wounded at least 36 Iraqis, three Americans, an Australian and an Icelandic.
