Two individuals planning to carry out suicide attacks have been detained in Kabul in the last week, the National Directorate of Security said in a statement on Wednesday.
"The suicide bombers belong to the Haqqani network and were planning to carry out terror attacks on Presidential candidates' campaigning in Kabul city," the statement said. "They were detained before they reached their target."
The group was carrying suicide vests and numerous weapons and explosives, the statement added.
There has been a steady flow of attacks around Afghanistan since the new year, including in the normally secure capital, suggesting the usual spring-to-fall "fighting season" paradigm normally operated under by coalition and Afghan forces would not be in play this year.
The Ministry of Interior on Wednesday announced that in a separate operation by Afghan forces two people planning a suicide attack were detained in Kunar province on Tuesday.
The two detained individuals have confessed in questioning that they were sending insurgents across the border for carrying out suicide attacks in the Nari district of Kunar province, while the election process is underway.
Officials from the Ministry of Interior recently announced that special precautions had been taken for preventing insurgent attacks during the Presidential campaigns running through mid-March.
