A suicide bomber killed three people including a police constable in Pakistan's main northwest city of Peshawar, police said Monday.
Police official Shaukat Khan said five other people were wounded in the blast Monday at Pathang Intersection on the well-known Ring Road around the troubled city. Television footage showed a destroyed rickshaw surrounded by security officials.
No group immediately claimed responsibility, but Islamist militants have staged numerous attacks in Pakistan over the past five weeks. Some 300 people have been killed.
The attacks appeared to be aimed at undermining the government's resolve in its offensive against the Taliban in the South Waziristan tribal region.
