At least five militants, including a key commander, were killed and three others injured Wednesday in a blast in Pakistan's South Waziristan, officials claimed.
The incident was in continuation of the ongoing infighting between rival factions of the Taliban, Dawn online reported citing official sources.
The killed militants have not been identified yet.
Earlier, clashes between the Sajna and Shehryar Mehsud groups left scores of militants dead, the report said.
