A bomb has been detonated inside a mosque in eastern Afghanistan, wounding at least twenty-two people, including a candidate in the upcoming parliamentary elections, Press TV reported.
Local officials say the explosion was caused by a mine placed inside the mosque during Friday prayers.
The blast seriously injured the candidate, Sayedullah Sayed, who was making a speech in the mosque at the time, AFP reported.
The injured were taken to a hospital in nearby Khost city.
The incident took place in Bahramkhail, a village in Khost province's Ismailkhail district, on the eastern border with Pakistan, said General Nawab Khan, the commander of the coordination body for Afghan and NATO forces in Khost.
Afghanistan is scheduled to hold national parliamentary elections in September despite fears that a surge in Taliban militant attacks and clashes with international forces could undermine security for the elections.
There were isolated attacks on voters and polling stations in August's presidential election.
