He confirmed that 89 people, including 13 Afghans, were killed in the twin blasts.
The interior ministry official specified that 36 men and 53 women were killed in the tragic event, from whom 9 were children and 30 were 18.
Mirahmadi also said that some people have been arrested in connection with the attacks in 5 cities in 5 provinces. The detailed report on the arrests will be issued by security bodies in the coming hours, he added.
