UPDATE May 27, 10:49 a.m.: The Islamic State group has claimed responsibility for an attack on Coptic Christians traveling to a remote desert monastery south of Cairo that killed 29.
The group's news agency, Aamaq, said on Saturday that an IS unit targeted the bus the previous day and put the death toll at 32.
Egypt responded to the attack, the fourth since December by IS to target Christians, with airstrikes against what the military says are bases in eastern Libya in which the militants have been trained.
