Mughrabi and James Mackenzie JERUSALEM/CAIRO (Reuters) -Israeli warplanes and artillery attacked the northern Gaza Strip on Sunday and Palestinian medics said eight people were killed shortly after Israel and Hamas missed a deadline for a ceasefire that could pave the way for halting the Middle East's most devastating conflict in years.

Israeli Prime Minister Benjamin Netanyahu said the cease-fire would not begin until Hamas provides the names of the three hostages it was set to release later Sunday in exchange for scores of Palestinian prisoners.
