A suicide bomber has targeted an intelligence office in eastern Afghanistan, killing six people and wounding at least 40.
A spokesman for the governor of Nangahar Province said a truck packed with explosives had blown up at the gate of the Jalalabad office of the National Directorate of Security in the eastern city of Jalalabad early on August 30.
The Taliban claimed responsibility for the attack.
The violence comes amid a political deadlock with rival presidential candidates have been unable to resolve months-long disputes over an election meant to mark the first democratic transfer of power in Afghan history.
Most foreign combat troops are due to leave by the end of the year but the deadlock over the presidential election has further delayed the signing a security pact with the United States governing how many troops would remain.
