(Reuters) - Combat between Israeli troops and Hamas militants raged on Monday as Israel pressed home its ground assault in Gaza in the face of French-led diplomatic efforts to broker a cease-fire.
Here is a timeline of events since early December:
December 14 - Hamas leader Khaled Meshaal says the group will not renew a six-month-old truce with Israel.
December 18 - Hamas declares the end of the Egyptian-brokered cease-fire, which expires the next day with a surge of cross-border fighting.
December 24 - Gaza Palestinian militants ratchet up rocket fire towards Israel.
December 27 - Israel launches massive air strikes on Gaza in response to the intensified rocket and mortar fire killing at least 229 Palestinians.
December 28 - Hamas says an Israeli air strike destroys a laboratory building at the Islamic University, a significant cultural symbol of Hamas.
-- Israeli aircraft bomb some 40 smuggling tunnels in the Gaza Strip that provide a lifeline to the outside world.
December 29 - Israel steps up its air strikes and bombs the Hamas-run Interior Ministry, the first air strike targeting a government building in the offensive.
-- Israel declares areas around the Gaza Strip a “closed military zone.”
-- Palestinian militants fire rockets deeper into southern Israel.

-- Palestinian casualties since December 27 are 412 dead and about 1,850 wounded. A U.N. agency says about a quarter of the dead are civilians.
-- Three Israeli civilians and a soldier have been killed by Palestinian rockets since the air strikes began.
January 2 - No sign of a cease-fire on the seventh day of the conflict, with at least 429 Palestinians killed and 2,000 wounded, but a Palestinian official says that Egypt had begun exploratory talks with Hamas to halt the bloodshed.
January 3 - Israel launches a ground offensive in the Gaza Strip, sending tanks and infantry into battle with Hamas fighters who had defied eight days of deadly air strikes.
