The suicide bombing came just days after the U.S. government barred U.S. citizens, U.S. companies and foreign companies operating in the United States from doing most business with the Hamas-led Palestinian Authority. Last week Oxfam International warned that the humanitarian crisis in the West Bank and Gaza will only worsen as the international community cuts off aid and contacts with the Palestinian Authority. According to Oxfam over 60 percent of Palestinians live on about two dollars a day.
