Israeli PM Netanyahu said Hamas had not lived up to its commitment to provide the names of the three hostages it was set to release later on Sunday in exchange for scores of Palestinian prisoners.

The ceasefire was delayed after Israel said Hamas had failed to produce the names of the first three hostages expected to be released on Sunday under the truce.

A ceasefire in Gaza has come into effect, putting a halt to more than 15 months of devastating war. The agreement was set to be enforced earlier Sunday but was delayed by almost three hours when Hamas failed to provide on time the list of three female hostages that it would release on the first day.
