Afghan officials say security forces have killed a suspected suicide bomber in Kabul near the site of this week's upcoming assembly of tribal elders, or loya jirga.

Authorities say the man, shot dead Monday, was carrying a bag of explosives.

The Taliban in Afghanistan said Sunday it has acquired the security plans for the loya jirga where the elders are expected to make decisions on future ties with the U.S.

Afghan officials have dismissed the documents, published on a Taliban website, as fake. They say the material is a scare tactic, designed to intimidate participants coming to the meeting.

The Taliban said on its website the group had received the plans from its personnel “embedded inside the enemy ranks.”

The Taliban attacked the last loya jirga in 2010.
