Gaza was inundated with Israeli tanks Saturday as the ground offensive against Hamas in Gaza's eastern border continued into the weekend. 

Israel sent ground troops into Gaza Thursday after fighting Hamas by air for 10 days. Israel failed to stop the barrage of rockets from being launched into Israeli towns, prompting the Israeli government to order a large-scale ground invasion. 

The Israeli military said its engineers are focusing on a 1.5 mile wide buffer zone in an effort to destroy rocket launch pads and tunnels that were dug by Hamas militants after the last violent conflict in 2012.

A spokesman for the IDF said that 13 tunnels and 95 rockets launches were found and destroyed in an Israeli raid. Searches are continuing for more rocket launchers and other weaponry.  

Hamas militants used one of the tunnels to get into Israel Saturday, according to Reuters. The IDF said they confirmed the incident and killed one militant while staving off the rest. Four Israeli soldiers were also wounded in the offensive. 

Palestinians also launched 18 rockets into Israel Saturday, killing a man and wounding four people, including two children. The people wounded live in a southern Bedouin Arab village. 

According to Gaza officials, at least 325 Palestinians, including 70 children, have been killed in the bloody conflict. 

"I live in fear expecting death. I no longer know what's more difficult - to die or to await death," Ali Mahmoud, a 40-year-old resident of the northern Gaza town of Beit Hanoun, told Reuters. 

One Israeli soldier and two Israeli civilians have died in the fighting. 

The tensions began when three Jewish Israeli teenagers were abducted and murdered. Hamas neither confirmed nor denied involvement in the killings. The fighting then started after a Palestinian teen was kidnapped and killed in Jerusalem in an apparent revenge killing. 

Officials in Gaza claim that attacks from Israel killed 33 people in Gaza Saturday, mostly civilians, in Beit Hanoun, Beit Lahiya and Khan Younis. 

The IDF did not immediately confirm the attacks, but it did confirm attacking 37 rocket launching sites Saturday.

Israel said that it strives to avoid civilian casualties and that Hamas uses people as human shields by launching rockets from heavily populated areas. Israeli officials have said that Hamas kills their own people to garner international sympathy for their plight. 

The military said that troops raided a house in Beit Lahiya and killed a gunman after he wounded three soldiers. Islamic Jihad, another militant faction, also fought alongside Hamas militants. 

Israel said that more than 1,500 rockets have been fired into civilian towns in Israel during the fighting but that Israeli casualties have been low because of the rockets' inaccuracies, as well as Israel's sophisticated Iron Dome missile defense system that intercepts rockets at a 90 percent success rate. 

So far, there have been futile attempts to implement a cease-fire agreement. 

Egypt facilitated a temporary cease-fire, but it was violated when Hamas launched more rockets into southern Israel. 

Egypt will not revisit its cease-fire proposal, which Hamas has rejected. 

Palestinian President Mahmoud Abbas has spoken about wanting to implement a cease-fire. Abbas is traveling to Qatar on Saturday to see the emir of the state, and it is possible that he could meet with Hamas' leader, Khaled Meshaal, who lives in exile in Qatar. 

The Israelis prefer that Egypt intervene, as Egypt also views Hamas as a terrorist group because of its relationship with the Muslim Brotherhood. 

The United Nations said that more than 50,000 Palestinians had taken refuge from attacks in Gaza buildings. 

Palestinian officials said that 90 percent of the electricity in Gaza has been cut off. Israel said a Palestinian rocket downed a power line to Gaza from Israel but that they would not put engineers in danger by sending them to repair the line. 

Hamas said they will not stop firing rockets until embargoes by Israel and Egypt are lifted and other demands are met. Israel said they will not yet stop the offensive, although they do not realistically expect to completely dismantle Hamas.
