In what some are calling one of the deadliest attacks in the 10-month war in Gaza, an Israeli airstrike on a school-turned-shelter killed at least 100 people. Gaza officials say most of the dead were civilians. Israeli authorities say their soldiers killed dozens of militants in an attack that targeted a Hamas command center. Tahani Mustafa, an analyst at the International Crisis Group in Amman, discusses the complexities of the strike with host Marco Werman.
