Iraqi officials say an apartment building has collapsed in a southern town near the Kuwaiti border, killing four people and injuring at least six others. The mayor of Zubair, Abbas Rashim, says rescue teams are searching for people who might still be trapped in the rubble after Monday morning's collapse. A hospital official says two children were among the dead, according to a report of the Associated Press. Zubair is just south of the port city of Basra. It is 355 miles (570 kilometers) south of Baghdad.
