The bombing of a hospital in Gaza City has killed hundreds of people and escalated the ongoing conflict between Israel and Hamas.
Both sides blamed the other, but horrific scenes of the wounded ignited street protests in capitals across the region.
Israel's aerial bombardment campaign over the Gaza Strip is part of what it calls a total siege. This includes cutting off water, food and electricity supplies to a population of two million people. Human rights groups have criticized the siege for breaking humanitarian law.
U.S. President Joe Biden has said he plans to address the humanitarian crisis for Palestinian civilians when he visits Israel and Jordan this week.
Israel's military operation in Gaza, is in response to a brutal terrorist attack in Israel by Hamas Oct. 7 that killed at least 1,000 people, including Americans. The Israeli government says that Hamas is still holding at least 199 hostages kidnapped from Israel.
The Committee to Protect Journalists said at least 17 journalists have been killed in the Israel-Hamas conflict. Of the known deaths, the CPJ said 13 were Palestinian, three were Israeli and one was Lebanese.
It said eight journalists have been injured and three have been reported missing or detained.
The nonprofit said it continues to investigate "unconfirmed reports of other journalists being killed, missing, detained, hurt or threatened, and of damage to media offices and journalists' homes."
"CPJ emphasizes that journalists are civilians doing important work during times of crisis and must not be targeted by warring parties," said Sherif Mansour, CPJ's Middle East and North Africa program coordinator. "Journalists across the region are making great sacrifices to cover this heartbreaking conflict. All parties must take steps to ensure their safety."

The U.S. State Department advised Americans against traveling to Lebanon, citing an unpredictable security situation due to kidnappings, unrest in the wake of the Israel-Hamas war and "rocket, missile, and artillery exchanges" between Israel and Hezbollah.
The department raised its travel advisory for Lebanon to level 4, the highest on its rating scale, and warned that the embassy in Beirut has limited capacity to support U.S. citizens there.
State currently has a level 4 travel advisory for Gaza, citing terrorism, civil unrest and armed conflict. It has a level 3 advisory for Israel and the West Bank, recommending Americans reconsider traveling due to terrorism and civil unrest.
