GAZA CITY, Gaza Strip (AP, MyNews4.com & KRNV) -- A three-day ceasefire in the Gaza Strip has gone into effect following heavy Israel-Hamas fighting.
The ceasefire, announced hours earlier by the U.S. and the U.N., took effect at 8:00 a.m. (0500 GMT) Friday. Secretary of State John Kerry cautioned there were "no guarantees" that the lull would bring an end to the Gaza war, now in its fourth week.
Israel and Hamas both said they would respect the ceasefire but would respond to attacks.
At least four short humanitarian cease-fires have been announced since the conflict began, but each has been broken within a few hours by renewed fighting.
Hours before the ceasefire was to take effect, 17 Palestinians were killed in Israeli strikes. Israel's military said five soldiers were killed along the Gaza border the previous evening.
