infrastructure in a neighborhood in northwest rafah. it's a stunning incident for israel and one of the deadliest days for the idf since teuber seventh, the short time ago, people gathered for a moment of silence to pay their respects for the eighth lives lost. cnn's oren liebermann is joining us now, live from a haifa israel or and what are you learning fredricka as you point out, this is one of the single deadliest incidents we've seen against israeli soldiers in gaza since the beginning of the war, a total of eight soldiers were killed. >> one of those has been identified to this point, a captain who was with those eight soldiers who are part of a combat engineering brigade, the idf says this is still under investigation, but according to what they know, now, there was an explosion from what they call a sidebar them near their armored personnel carriers. so an armored vehicle. now they don't explain what a sidebar is, whether it was something affixed to the vehicle itself or a strike armored personnel carrier. the case from the side, regardless, the idf says there were materials carried by that combat engineering unit as they were moving early in the morning and at 5:15 this morning. and that may also exploded perhaps triggered itself by the sidebar that in and of itself is a problem because those flows of materials carried by the combat engineering unit are not supposed to explode so this is under investigation to figure out exactly what happened here first, make sure this never happens again, but also get a better clarity on how it happened. the idf says the explosion was so large that it became very difficult to identify and locate the soldier's. meanwhile, the al-qassam brigades, that is hamas military wing, say they let a complex trap for the idf unit there in northwest rafah. >> they say first-day targeted a military bulldozer. >> and then when the rescue unit came in in an armored personnel carrier, that's when they attacked the armored personnel carrier again, for the idf, this is still under investigation. meanwhile, as you point out not only one of the single deadliest incidence of the war, but it's also one week since the rescue effort in which four israeli hostages were rescued. so all of that is kind of mixing together here. and daniel hagari, the rear admiral, who is the spokesperson for the idf. pointed out, first, of course lamenting the loss of lives, but also saying in terms of the rescue effort, unfortunately, not everyone can be rescued like that. again, perhaps not anyone can be rescued like that again. and meanwhile, once again, we see anti-government protests in tel aviv and jerusalem. and in other places. so that is the status as we look around, you here on a saturday night. >> all right. oren liebermann, thank you so much. we'll check back with you. >> let's talk further with cnn global affairs analyst mark esper. >> he was the defense secretary under former president trump secretary esper good to see you. so let's begin with this incident. now being described in rafah. you heard are oren liebermann reporting on what's been described as a sizable explosion that perhaps this is part of a complex trap. a side bomb that may have triggered an explosion of these the engineer during tools of what are the armored vehicles, how do you assess this right now yeah. >> good afternoon, fredricka. obviously it's a tragic incident that happened, but it looks to have been a complex ambush by hamas. first loring in the bulldozer and armored bulldozer and its crew destroying it and then waiting to ambush. again, an armored personnel carrier with idf soldiers who came to rescue them and then they ambushed them as well. so fairly more details to follow, but this is the nature of urban combat, where you're fighting you know, 360 degrees and above and below you in in gaza where you have enemy coming out of the tunnels beneath them. so there'll be much to learn in the coming days about what happened. and i'm sure the idf to be taking actions to make sure it doesn't happen again, because as we know, they could do to conduct operations in central and northern gaza and the ongoing operations in rafah remains. so this and this war isn't ending anytime soon. >> and what does this tell you about this conflict? i mean, now seven months after october 7 this is the deadliest de for the idf since october 7, eight israeli soldiers killed well, in warfare, each side continues to adapt as to one another as innovations on the battlefield tactically are developed and employed we had thought some time ago that maybe hamas had moved, shifted away from a fixed formations battalions, companies, and platoons. >> and we're transitioning more to it and insurgency, where they were conducting hit and run raids with 1234 men are so. maybe this is part of that. maybe it's not, but this may be another turning point in the conflict in terms of the tactics on the ground. it doesn't necessarily affect the operational piece of it that is that the idf wants to continue to go through rafah trying to find not only hostages, but hamas leadership. knock out the remaining battalions and the underground infrastructure that will continue until, until the key tasks are accomplished. but on the tactics that happens block-by-block, building by building they will continue to adapt and develop and this has come now, just two weeks after the biden administration detailed a potential ceasefire agreement. >> and your view does this undermine any hope there may have been that there could be an agreed upon ceasefire no, i don't think so. >> i think if anything that brings together the israeli people you saw from orange solid reporting that people had gathered to mourn the loss of the soldiers. i think it brings them together. look, i'm frankly not confident that don't believe that hamas wants to cut a deal because or that a deal is possible between them and israel because the two key things that they want are in contravention of one another. hamas wants israel completely out of gaza, and they want the war to, and they want a permanent end to the war. and israel doesn't want either of those because they want to continue the conflict. they want to get rid of hamas, and they want to make sure hamas never comes back to govern, to rule gaza once again, those two key aims are in conflict with one other end hamas is never going to give up the money most important leverage it has, which are the hostages, which interestingly, and we've talked about this before. i think nobody knows how many those costs just are still alive could be 75, we think is the best number, but could be far fewer. and i hate to say that, but hamas is planning their hand pretty aggressively when it comes to these negotiations. but i don't see them at the end the day willing to agree to a deal. >> okay. >> let's turn to switzerland now, where more than 100 countries and organizations are meeting for ukrainian peace summit notably absent russia and china in a short time ago ukrainian president zelenskyy said that any peace proposal agreed to by the attendees would be submitted to russia. but realistically is a peace deal achievable if russia is not involved in these talks in your view? >> no i don't think so. and also because russia right now arguably has the upper hand in the conflict, they've had momentum the last several months. it's probably stalled and last 30 days or so as new american weapons and ammunition of arrived on the battlefield but i don't see putin coming to the table until he sees, until he's losing leverage and zelenskyy gains upper hand. and of course strategically we believe that putin is waiting to see what happens in the us election in november the view is if donald trump wins, putin will be in a better situation. these are these, the conflict. >> now, i say all that, but it's important to note also that this peace conference in switzerland began with a great gusto when to its back. >> and that was coming out of the g7 summit where the g7 liters took an aggressive stance are more aggressive stance against russia with regard to committing to provide that military and economic funding for the next ten years. and by the same token, took a more aggressive stance with regard to china criticizing them in multiple accounts with regard to their supply of dual use items to the conflict. and then also took them to task with regard to economic i'll make matters as well that affect the g7. so very interesting confluence events from the g7 moving into this peace conference. >> yeah. and then even in switzerland, that moment we just saw the handshake with zelenskyy and vice president kamala harris and she also announced a 1.2 billion dollar boost in aid for you cranes to humanitarian and energy needs how influential you believe that's going to be and helpful to ukraine? >> will it be it's all very helpful. >> anything helps this point. it is signaling support to ukraine and to presence lenski from the west, from the united states european allies, and by the way, our partners in the indo-pacific as well. all these things matter. they send the right messages to the cranium. they send the right messages to moscow as well. and then in a few weeks fredricka will have the washington summit, which is a gathering of all nato allies. it will happen in dc. and that, that is where you'll see more support expressed for ukraine. you'll see security guarantees revealed at talked about what that will mean for zelenskyy in the coming years. and again, more messaging gets putin that the democracies of the west are going to stand up to russian aggression. so this is going to be a busy period from here going into the washington summit, three weeks. >> all right. former secretary mark esper. thank you so much. >> thanks, fredricka right now, russia has a fleet of war ships docked in havana, cuba, just 90 miles from
