Pakistan, April 29, 2013.

Pakistani authorities say a bomb attack has killed at least five people in the northwestern city of Peshawar, as violence in Pakistan spikes ahead of May 11 parliamentary elections.

Police said Monday's bomb attack hit both a police vehicle and a bus passing by on one of the city's busiest roads. Reports say a police commissioner had just passed by, but was not hurt.

Police said they believe it was a suicide attack carried out by a man on a motorcycle. No group has claimed responsibility.

At least 30 people are being treated for wounds following the attack.

On Sunday, three Taliban bomb attacks in northwest Pakistan killed at least nine people at political campaign offices.

In the month leading up to the May 11 elections, a wave of political violence has killed dozens of people, with most of the attacks targeting candidates from secular parties opposed to the Taliban.

The Pakistani Taliban claimed responsibility for Sunday's attacks, as well as two blasts Saturday against secular parties in Pakistan's largest city of Karachi. At least three people died in those attacks.

The May 11 elections will be the first time a Pakistani civilian government has served a full term and passed government leadership on to a new civilian administration.
