In pictures: Israel-Gaza conflict intensifies with rockets, airstrikes

Residents sought shelter as airstrikes by the Israel Defense Forces (IDF) continued. One airstrike Sunday killed 33 people. Israeli authorities say the attacks target Hamas officials and that the humanitarian tragedy is the result of party leaders' mixing with the civilian population. Gaza's Health Ministry reports 181 deaths, including 52 children; 10 people have been killed in Israel.

The IDF warned media such as the AP and Al Jazeera before destroying the 12-story building that housed their offices and several apartments, saying Hamas operated there. "We have called on the Israeli government to put forward the evidence," AP CEO Gary Pruitt said. "AP’s bureau has been in this building for 15 years. We have had no indication Hamas was in the building or active in the building."

On Thursday, Israeli fighter planes bombed the southern Gaza Strip. According to the IDF, the attacks targeted facilities that housed members of the Hamas organization.

This building, destroyed on Wednesday, was one of the first to fall when the IDF's strikes on the alleged offices of militant groups or their leaders began.

Residents of Gaza evacuated their homes on Tuesday, early in the conflict, which has only spiraled since.

Hamas, which rules the Gaza Strip, began firing rockets into Israel earlier in the conflict. Israel's missile defense system has protected Tel Aviv and other areas — destroying projectiles in the air or diverting them so they cause as little damage as possible.

But the Iron Dome missile defense system does not offer 100% protection. When the sirens go off, Israelis know that they have to find safety in shelters as quickly as possible. Even if it's 3 a.m.

People who fail to make it to shelters in time try to take cover as best they can, like these people in Ashkelon, about 10 kilometers (6 miles) north of the Gaza Strip, on Tuesday.

Even if rockets can be repelled, falling debris is also dangerous. Here, a house in Yehud, just north of Israel's Ben Gurion Airport, has been destroyed. The Israeli army has claimed that more than 1,000 rockets have been fired at Israel from Gaza since Monday.

In recent days, there have been many clashes between Palestinian demonstrators and Israeli security forces in several cities, including here in Hebron, in the West Bank, which is occupied by Israel. Demonstrators threw stones and other projectiles.

Security forces have used stun grenades, tear gas and rubber bullets against Arab Israelis protesting forced evictions in east Jerusalem.

Meanwhile, the Israeli military has been amassing combat troops and tanks on the border with the Gaza Strip, recalling the conflicts in 2008/2009 and 2014.

It doesn't look as if either side will de-escalate the tension any time soon. Some Palestinians in Gaza City have taken refuge at the UN compound for fear of further airstrikes.
