The family of the suicide bomber who attacked a CIA base in Afghanistan last week has revealed new details about his background. In an interview with the New York Times, a brother of Humam Khalil al-Balawi said their family had last heard from Balawi when he was volunteering as a medical doctor to treat wounded Palestinians in the Gaza Strip. The brother says Balawi was “changed” by Israel’s three-week assault on Gaza that killed over 1,300 Palestinians.
