With the situation in Gaza continuing to escalate, the broadcast news divisions are making sure their people are in the region. Additional changes may be made, but for now here is the latest on the assignments in Gaza, Israel and beyond.

ABC News has Christiane Amanpour in Jerusalem, joined by Lama Hasan. Matt Gutman is reporting for ABC from Tel Aviv, while Alexander Marquardt reports from Gaza.

NBC News has Ayman Mohyeldin and Richard Engel in Gaza, Stephanie Gosk and Martin Fletcher in Tel Aviv, Jim Maceda in Cairo, Egypt and Ali Rouzi in Tehran, Iran.

CBS News has Clarissa Ward reporting from Cairo, Charlie D’Agata reporting from Gaza and Allen Pizzey reporting from Israel.

Fox News has Jerusalem correspondents Leland Vittert and David Lee Miller reporting from southwestern Israel, near the Gaza border.

New developments in Libya this morning, with the French military taking action, are keeping the U.S. cable news channels active.

Beginning at 11amET, CNN and CNNI began another simulcast of coverage with anchors T.J. Holmes of CNN and John Vause of CNNI covering the news. Correspondents Nic Robertson and Arwa Damon are in Libya, Ed Henry is in Brazil and Jim Bitterman and Jill Dougherty are in Paris.

Fox News Channel’s Neil Cavuto was already in for a live Saturday morning show on the economic recovery efforts following the earthquake/tsunami in Japan. He kept cameras trained on both Brasil — where President Obama was about to speak alongside Brazilian president Dilma Rousseff and on Paris, where Secy. of State Hillary Clinton was preparing to speak after meetings on the NATO action in Libya. Rick Leventhal and Steve Harrigan are in Libya (spooked by anti-aircraft fire during one live report today. Video after the jump.)

MSNBC went into the NoonET hour with anchor Richard Lui, as Pres. Obama was appearing with Pres. Rousseff. Correspondent Mike Viquiera is in Paris, Chuck Todd is in Brazil and Jim Maceda is in Libya for NBC/MSNBC.

None of the networks had a Brazilian interpreter during Pres. Rousseff’s lengthy opening statement. And just as the president was about to speak, all three networks lost the signal from Brasilia. It returned after about 3 minutes.

Cavuto stayed live until 12:17pm telling the audience, “We just wanted to keep you abreast not only of developments in the political world but certainly in the business world. We hope we served bot those audiences today and we appreciate our normal ‘Cost of Freedom’ audience being patient as we attempted both.”

> Update, 2:18pm: ABC’s Diane Sawyer is coming in to anchor “World News.” Regular weekend anchor David Muir will report, as will Christiane Amanpour, Martha Raddatz, Jake Tapper, and Alex Marquardt, in Libya.

> Update, 3:39pm: Sawyer also anchored a special report (right) on the news of U.S. military involvement.

> More: CBS’s Russ Mitchell has anchored three special reports today at NoonET, 2:36pm, and 3:59pm during CBS coverage of the NCAA tournament.
