At least three journalists were injured by Israeli airstrikes on buildings housing media outlets, the Committee to Protect Journalists said on Friday.

"The Israel Defense Forces know where media outlets are located in Gaza and must ensure that they are not hit as part of its offensive," said CPJ Middle East and North Africa Program Coordinator Sherif Mansour.

"Attacking media outlets is a violation of international law and denies journalists their right to protection as civilians in war zone."

Those injured includes Muhammad Shabat, a cameraman with Watania Media Agency, Ahmad al-Ajala, host of Sawt al-Watan radio station, and Tariq Hamdieh, correspondent for the same station.

The reports follow the death of Hamid Shihab, a driver for a Gaza-based news agency, who was killed last week in an Israeli airstrike while driving in his car.

“TV” was spelled out in big letters on the hood of the car.

The Israeli Defense Forces are reportedly requiring journalists entering Gaza to fill out a form that absolves the Israeli army of all responsibility in the event of injury or death.

The form, tweeted by The Huffington Post’s Sophia Jones, was given to reporters in a convoy of press entering Gaza through the Erez Crossing.

At erez crossing, reporters crossing into #gaza are made to sign form absolving IDF of any responsibility if press gets hurt/worse. — Sophia Jones (@Sophia_MJones) July 18, 2014

Reporters entering Gaza today made to sign a disclaimer saying that Israeli MOD & IDF bear no responsibility for their injury/death. — Louisa Loveluck (@leloveluck) July 18, 2014

The form reads:

I am aware that neither the MOD nor the IDF shall bear any liability whatsoever for damage or [unreadable] resulting from military operations in and around Gaza or otherwise caused to my person or [p…] during, or as a result of, my presence in or entrance to Gaza.

The form continues to state that the signee shall no sue the MOD or IDF for damage sustained during, or as a result of, their presence or entrance to Gaza.

Additionally, the form says the signee agrees to compensate the IDF should any individual or company sue the IDF on their behalf.

An IDF spokesperson tells Mashable the forms are warranted due to the unique situation in the Gaza Strip.

"The current security situation requires special measures at the Erez crossing,” Perle, an IDF spokesperson, says. “The IDF has asked foreign journalists to sign a form acknowledging their understanding that they are entering an active conflict zone and the dangers this entails.”

Forms like this are common for reporters stationed in conflict zones. The U.S. military required all journalists to sign a similar form when they were reporting in Iraq.

Louisa Loveluck, a Cairo-based correspondent for CS Monitor and the Telegraph, says it's been standard practice on some crossings since 2012, she tweeted on Friday in discussing the document.

A former humanitarian worker told Mashable she signed a similar form to enter Gaza back in 2006-2007. “Ruler rules,” she said.

A previous version of the so-called “waivers” were heavily criticized when they surfaced back in 2003, when Amnesty International refused to sign them — and thus were prevented from entering Gaza. The organization condemned them.

Amnesty International is "categorically opposed to any attempt to get people to sign away their rights," the organization said in a statement at the time. "The signing of 'waivers' does not absolve the Israeli army of its responsibility in any way, nor the Israeli authorities of their duties to ensure that armed forces respect human rights in all circumstances,” it said.
