Preparing for a ground war --- Israeli forces position themselves along Gaza's border making an invasion that much more likely. The cabinet has mobilized up to 75,000 reservists in anticipation.

Explosions rocked Gaza on Saturday. Locals put out a fire after an Israeli air strike destroyed a building. Palestinian officials say one person was killed and several were injured.

More than forty people have been killed since the strikes began several day earlier, the majority of them Palestinians. Three Israeli civilians were killed on Thursday.
