After deadly Easter attacks, Sri Lankan officials blame jihadists, admit they had warning

Summary: A wave of suicide bombings in Sri Lanka on Easter Sunday has the country grieving, on edge and under a national emergency. At least 290 people died in the attack, which the government blamed on a little-known Jihadist group. Police arrested multiple suspects and worked to disarm additional bombs, as officials admitted they had ignored warnings of an attack weeks before. Judy Woodruff reports.
