Baquba: The death toll from a suicide bombing at a coffee house in central Iraq's restive Diyala province has risen to 30, a medical official said on Saturday, making the deadliest attack in October.

Friday night's bombing in the town of Balad Ruz also wounded 68 people, according to Ahmed Alwan, a doctor at the general hospital of Baquba, the provincial capital of Diyala.

"The final toll from Friday's bombing is 30 dead and 68 wounded. All the dead are men, but the wounded include three women and two children," Alwan said.

Balad Ruz police chief Major Ahmad Al Tamimi had given on Friday a toll of 25 dead and 70 wounded "when a suicide bomber detonated a belt filled with explosives at a coffee house in the centre of the city."
