“Ansarul Muhajideen, a jihadist group in Pakistan known to include Uzbek fighters, claimed credit for a suicide attack in the Taliban-controlled tribal agency of North Waziristan today that killed two paramilitary Frontier Corps troops. The group’s spokesman said the attack was carried out to avenge the death of former Movement of the Taliban in Pakistan emir Hakeemullah Mehsud, who was killed earlier this month in a US drone strike.”
