At least 25 people were killed and 18 injured in Thursday's bomb attack on funerals for Iraqi fighters killed by extremists in Salaheddine province, AFP reported Friday (April 13th).

"Two bombs exploded as the funeral procession was entering the cemetery" in Sedra, village mayor Salaheddin Shaalan said.

The Sunni village is south of al-Sharqat, one of the last bastions of the "Islamic State of Iraq and Syria" (ISIS) in the country's north to be retaken by Iraqi forces.

"In total, 25 people were killed and 18 injured, four of whom are still in critical condition," a police officer told AFP on Friday, on condition of anonymity, revising an earlier death toll.

Medical sources confirmed the new figures.

It was the deadliest attack in Iraq since a January 16th double suicide bombing in Baghdad claimed 31 lives.

Thursday's attack took place during a funeral for five members of Iraqi paramilitary units killed Wednesday night in the same village.

Salaheddine governor Ahmed al-Jubury on Friday declared a two-day mourning across the province for the victims of the terrorist attack, the governor’s media office said in a statement.
