Insurgents pressing a campaign of violence in Iraq ahead of next month's constitutional referendum have killed five more people Friday in a suicide bombing at a Baghdad bus terminal.
Authorities say at least eight other people were hurt in the blast on a city bus.
The attack comes a day after Iraq's most influential Shi'ite cleric, Grand Ayatollah Ali al-Sistani, urged his supporters to vote "yes" in the October 15 national referendum.
In Washington, Saudi Arabia's foreign minister warned Thursday that Iraq is hurtling toward disintegration. Prince Saud al-Faisal told reporters he does not believe elections or a constitution alone will bring Iraqis together.
He said if Iraq is split into Shi'ite, Sunni and Kurdish states, it could drag other countries in the region into the conflict.
