>> thanks. today israel's military reported it had found some bodies of hostages kidnapped by hamas. and the state department raised the number of americans killed in the attacks to 29. cbs's reporter is at the white house with more on diplomatic efforts to contain the conflict. >> reporter: good evening, robert. this afternoon president biden spoke to israeli prime minister benjamin netanyahu and the president of the palestinian authority, mahmoud abbas. in both of those calls, the white house says he condemned the terrorist attacks by hamas and brought up the need for humanitarian aid to civilians in gaza. the incremental nature of diplomacy is up against the clock. >> none of us want to see suffering by civilians on any side, whether it is in israel, whether it is in gaza. >> reporter: as u.s. secretary of state antony blinken shuttles between israel, jordan, qatar, saudi, bahrain, and the united arab emirates, trying to limit back lash from allies and

anent fadda and the birth of hamas. it ended as the 1993 oslo peace accords brought forth peace for a future palestinian state. but frustrations led to a second even more bloody war. it was the withdrawal from gaza, leaving it to be ruled by the palestinians. the following year, palestinians angry with their government's corruption handed hamas an electoral victory. but rival israel and the united states rejected their rule. that same year hamas kidnapped israeli soldier who would eventually be exchanged for more than 1,000 palestinian prisoners. in 2007, hamas seized control of gaza during a civil war with fatah. the following years would see sporadic violence and major wars. but invading gaza by ground is something israel has only done twice. israeli forces entered cities in

2009 to stop rocket attacks and weapons smuggling. then in 2014, israeli forces led a shallow incursion. capturing territory along the gaza border to destroy smuggling and attack tunnels. every violent outburst ended in negotiations, but never addressed the underlying cause of the conflict. sowing the seeds of conflict. subsequent presidents tried but failed to bring peace through a two-state solution. >> nations that support a two-state solution -- >> an independent state -- >> my continued support, even though i know it is not in the near material, a two-state solution. >> reporter: a palestinian state was never a major priority for israeli priority benjamin netanyahu. >> it's never been about a palestinian state. it's always been about the jewish state. >> reporter: the palestinians have also rejected peace deals

in the past which leads us to this latest round of fighting. because in the absence of peace, there will be war. >> ian lae, thanks. last weekend's surprise attack has put israel's intelligence and security services in a harsh spotlight. even as militants fired thousands of rockets at israel, there was safety from above. cbs's david martin has more on the iron dome. >> reporter: an american transport plane unloading munitions at an israeli air field. american defense secretary lloyd austin walking the tarmac in a show of support. among the most critical items, interceptors for the iron dome defense system which has kept the death toll in israel from going even higher. >> including ammunition and interceptors to replenish iron dome. we're going to make sure that israel does not run out of these critical assets. >> reporter: iron dome has been

defending israel against terrorist rockets for more than a decade. >> it has been effective as it typically is in taking a lot of those rockets out of the sky and saving countless lives by doing so. of course, some rockets have gotten through to tragic cost. >> reporter: because the flight time for a rocket is so short, iron dome can operate on automatic. as soon as a rocket launch is detected, an alert goes out telling everyone to run for shelter while iron dome launches its interceptors, honing in only on rockets headed toward populated areas. >> so it doesn't have to fire 4,500 interceptors to shoot down 4,500 rockets. >> no. a significant fraction of these will not hit anything vital. >> reporter: the retired general frank mckenzie says hamas doesn't really care where the rockets land. >> they've got a large stockpile of missiles and i think we should anticipate the intensity

of these attacks to continue for a few days yet. >> reporter: an israeli invasion of gaza could eliminate the rocket launchers. but another terrorist organization, hezbollah, is based in lebanon on israel's northern border and has an estimated stock pail of $150,000 rockets and missiles. david martin, cbs news, the pentagon. straight ahead on the cbs weekend news, the tentative deal for health care workers as other workers prepare to expand their strikes. and camped out with all eyes on the sky during a rare partial ecl eclipse. plus, the art wist larger than life artwork.

too expensive. >> with no insight into the personal subscriber, it felt like a bridge too far to add this deep into the negotiation. >> reporter: george clooney says the actor's union is committed to hammering out a deal. >> we'll argue. we'll disagree. we'll figure it out and we won't leave until we get it done. >> reporter: while writers are back at work, industry experts say without actors, robert, it will take months to get a full slate of tv shows and movies. >> thank you. still ahead on the cbs weekend news, the rare celestial event turning the sun into a ring of fire.
