The violence in Israel and Gaza continued into its seventh day Monday as Hamas fired rockets into Israeli towns and Israel struck Hamas facilities in Gaza.

According to Haaretz, 172 Palestinians have been killed since Operation Protective Edge began, and more than 1,100 have been wounded. Gaza hospitals are in need of equipment and medicine for trauma injuries as the injured fill up hospital beds.

Yet, the Israeli Defense Forces issued warnings Sunday of incoming airstrikes so Gaza residents could evacuate homes and buildings. The IDF always issues warnings to civilian-heavy areas to allow time for evacuation.

Israel Defense Forces shot down a drone from Gaza Monday, according to Reuters. The drone was the first unmanned aircraft by Palestinian militants.

Hamas reportedly launched three unmanned aerial vehicles into Israel. One of them reached Kirya, the Defense Ministry headquarters located in Tel Aviv. According to Izz ad-Din al-Qassam Brigades, the military wing of Hamas, the group has created three different drone types: one for bombing missions, one for suicide missions and one for intelligence gathering.

Since the operation began, more than 700 rockets have hit Israel, a small number of which landed in cities. The Iron Dome, which is a device that intercepts rockets, has thwarted 87 percent of the rockets lobbed from the Gaza Strip.

Around six Israelis have been wounded since the beginning of the week-old war.

The fighting began after three Israeli teenagers were abducted and murdered in the West Bank and a Palestinian teenager was kidnapped and burned to death in east Jerusalem.

Israel has arrested three people, two of them minors, for the Palestinian teen's murder.

As of around 4 p.m. Monday, rocket sirens sounded in Sdot Negev, Sha'ar Hanegev and Eshkol Regional Council in Israel shortly after an Israeli soldier was wounded by a mortar shell that exploded in the Eshkol Regional Council. He was taken to the hospital for treatment. His wounds are not life-threatening.

The IDF also attempted a targeted killing mission in Khan Yunis. The target was riding a motorcycle when the strike occurred and was wounded. A second strike was stopped when the IDF spotted civilians in the area. According to the Israeli military, the intended target helped launch rocket fire into Israel in the past week.

Earlier Monday, six rockets were fired into Ashdod, Israel. Four of the rockets were intercepted by the Iron Dome, one exploded in an open area and another exploded in the yard of a home, where an 8-year-old boy was wounded by shrapnel.

Defense Minister Moshe Ya'alon held a briefing before noon Monday with representatives from the IDF and government officials Monday.

Haaretz reports that Ya'alon said Israel is "continuing to pound Hamas and its infrastructure."

"The damage to Hamas and to the other terror organizations in the Gaza Strip is severe. ... When Hamas leaders come out of their hiding places, they will discover the extent of the destruction and damage we have caused to the organization, in a way that will make them regret they embarked on a round of fighting with Israel," he said.

He added that Israel will not tolerate rocket fire from Syria and Lebanon, and that they will "respond aggressively" to such attempts.

One member of the Knesset, aka the Israeli government, spoke out against Israel Police Commissioner Yohanan Danino and the IDF offensive. MK Jamal Zahalka told Danino that his hands are "covered in blood." MK Miri Regev of Prime Minister Benjamin Netanyahu's Likud party shot back, calling Zahalka a "terrorist."

The inner cabinet also met Sunday to discuss a potential ground operation in Gaza. As of Sunday afternoon, 42,000 IDF reservists were authorized by the Israeli government to prepare for a possible ground invasion of Gaza.

Police also arrested 36 people Sunday for throwing rockets and firebombs in Jerusalem.

As the death toll mounts, the international community has called for a ceasefire to end what is the worst violence between Palestinians and Israelis in nearly two years.

The European Union said Monday, "All parties in the region," should halt violence. On Sunday, U.S. Secretary of State John Kerry also offered to help broker a truce between Gaza and Israel.
