ISLAMABAD - The Pakistani army entered the last of three Taliban strongholds targeted by its Waziristan offensive yesterday, as gunmen wounded a senior army officer and a soldier in the capital.

The operation in South Waziristan, the main Taliban and al-Qaeda sanctuary in Pakistan, has sparked a wave of retaliatory attacks that have killed about 300 civilians and security forces in the past month. The shooting in Islamabad was the third such attack in about two weeks.
