Kabul, Afghanistan (CNN) -- The death toll from a suicide bombing in northern Afghanistan has increased to 12, a spokesman for the governor of Faryab province said Saturday.
At least 26 were injured from attack at a crowded marketplace on Friday, Ahamad Jaweed Bedar said. Previously, a government official had said at least five people died and 35 were wounded from the blast.
Bedar said Rahmatiullah Turkistani, head of the provincial council, was targeted. The bomber approached the official with a petition when he blew himself up, a deputy to the governor of Faryab said Friday.
A guard for Turkistani -- along with 11 civilians -- were killed.
Friday is the traditional shopping day in the villages of Faryab.
