No big bombings, artillery strikes or rocket attacks were reported although Hamas and Israel both accused each other of sporadic shootings and other violations.
The ceasefire, which began at 7 a.m. (0500 GMT), involves the release later on Friday of 13 Israeli women and children held hostage by Hamas in exchange for Palestinian prisoners held in Israeli jails. Additional aid is to flow into Gaza, which has been gripped by a humanitarian crisis under weeks of Israeli bombardment that has killed thousands of Palestinians.
