artificial intelligence is now making its way into all aspects of our lives and in every corner of the world. take italy, for example. people there are very proud of their hand-made gelato. but one ice cream parlor is handing its recipes over to a computer, and customers are giving the new creations a thumb's up. tina kraus reports. >> reporter: italy has a centuries old love affair with ice cream.

and a gelato maker in milan is giving it a 21st century twist, churning out new flavors with the help of artificial intelligence. "we started using chatgpt," says john fraccosanpo, who owns the ice cream parlor. he says the ai tool helped to create a new frontier of flavors after they fed the chatbot a list of more than seven dozen current recipes. the first creation is white chocolate with a berry sauce, balsamic vinegar and carmelized black pepper, he says, a combination i never would have thought of. makers say skeptics stop complaining after the first taste. "i chose the two flavors created with artificial intelligence," this customer says. "i must say, this is very balanced, so it's very good." another ai special, vegan salt and sand blasted hazelnut with oat milk, and peaches sauteed in prosecco. massimo is credited as the ai

genius who put ai into the mix and says he is not worried technology will take his job way. he says chatgpt is not able to balance a recipe. so for the moment, my role is still fundamental. and chatbots can't eat it either, and that's sweet news for customers. tina kraus, cbs news. and just like that, craving some gelato. and that's today's "cbs news roundup." for some of you, the news continues. for others, tune in later for "cbs mornings" and follow us online any time at cbsnews.com. reporting from the cbs news broadcast center in new york city, i'm shanelle kaul.

. hello and thank you so much for staying up with us. i'm shanelle kaul in new york, and here are the top stories on "cbs news roundup." iranian-backed militia hezbollah is vowing revenge for a sophisticated attack involving hundreds of targeted explosions. hip-hop mogul sean "diddy" combs is behind bars, being held without bail in his federal sex trafficking case. and former president donald trump is back out on the campaign trail just days after escaping a second apparent attempt on his life. the iranian-backed militia group hezbollah is now blaming israel for a series of targeted

attacks across southern lebanon and syria on tuesday. hundreds of wireless pagers exploded simultaneously, targeting hezbollah members. at least 11 people were killed, including an 8-year-old girl, and more than 2700 injured, according to lebanese officials. hezbollah recently began using pagers to prevent cell phone tracking by israeli intelligence. this attack will escalate tensions in a region where israel for nearly a year now has been fighting its iranian-backed enemies in both lebanon and the palestinian gaza strip.lizabeth aviv with more. >> reporter: the pages exploded wherever hezbollah fighters happened to be -- in the street, at store checkouts, behind the wheel. in this bedroom, one blew a hole in the desk. ambulances rushed the injured to hospitals.

and emergency rooms filled with those injured by the tiny blasts powerful enough to shred faces and limbs. one high profile casualty was iran's ambassador to lebanon, who was slightly hurt. it too no time for hezbollah's tv station to pin the blame. "we hold the israeli enemy responsible," he says, "for this criminal aggression." hezbollah's leader hassan nasrallah had told his men months ago to get rid of their smartphones to foil israeli tracking. but the low-tech pager alternative has proved deeply embarrassing. ex-head of research at israel's foreign intelligence agency. so what's the psychological effect of this? what are the hezbollah commanders thinking tonight? >> that they are not safe anywhere, and this is something very difficult. they're not safe anywhere. their communication is not safe.

>> reporter: are they going to feel obliged to respond? >> i think they will retaliate, yeah. no question. . >> reporter: israel and hezbollah have been trading fire across the border with lebanon for months. we may just have seen the opening salvo in a much bigger war. everybody is wondering how the pagers were booby-trapped, and of course how they were detonated. we may not get answers to that for some time. but this was such a sophisticated piece of sabotage, the saboteurs got deep inside hezbollah's equipment supply line, that it must have been the work of a state. elizabeth palmer, cbs news, news, tel aviv. hip-hop mogul sean "diddy" combs is spending the night behind bars, remaining there until his trial on sex trafficking and racketeering charges begins. bail was denied on tuesday on grounds that he's a flight risk who could potentially intimidate

witnesses. cbs' michael george explains. >> reporter: a bombshell indictment against a man once at the top of the music industry, charging sean "diddy" combs with racketeering, conspiracy, sex trafficking by force, fraud, or coercion, and transportation to engage in prostitution, all of it prosecutors say occurring for decades, impacting multiple victims. >> combs used force, threats of force and coercion to cause victims to engage in extended sexual performance. the freak-offs sometimes lasted days at a time, involved multiple sex workers and often involved a variety of narcotics. >> reporter: damien williams says combs used his business enterprise and employees to facilitate these events. >> these events were allegedly recorded and the government has those recordings. that's going to make it extremely difficult if for diddy to defend himself if those recordings show coercion or violence. >> reporter: prosecutors showed images of weapons gathered from

the homeland security raids on combs' mansions in los angeles and miami back in march. the u.s. attorney also referred to the disturbing 2016 hotel video of combs assaulting former girlfriend cassie ventura, whose civil lawsuit set off a cascade of legal claims against combs. >> mr. combs is a fighter. he is going to fight this to the end. he is innocent. he came to new york to establish his innocence. he is not afraid. >> reporter: combs faces a mandatory minimum of 15 years in prison and as long as life behind bars if convicted on the three felony counts. michael george, cbs news, new york. the head of the secret service has reportedly told donald trump it is not safe for him to continue golfing without additional security measures. just days after another apparent attempt on his life, the former president was back on the campaign trail. cbs' skyler henry has more from washington. >> reporter: former president

donald trump returned to the campaign trail tuesday night for the first time since sunday's apparent assassination attempt at his west palm beach golf club. >> it's been a great experience. it's a dangerous business, however, being president. >> reporter: it's the former president's tenth visit to the battleground state of michigan during the 2024 campaign. >> we are going to bring so many auto plants into our country. you're going to be as big or bigger than you were 50 years ago. >> reporter: in the crucial state of pennsylvania, vice president kamala harris stopped by a voter registration training center in philadelphia. harris also spoke with members of the national association of black journalists. in a contentious interview with the same group weeks ago, trump raised questions about the vice president's race. harris called the former president a day after he said rhetoric from her and president biden is, quote, causing me to be shot at. >> i checked on him to see if he was okay. and i told him what i said publicly. there is no place for political violence in our country.

>> reporter: harris said trump is stoking fear in springfield, ohio, with his false claims about haitian immigrants there, including that they're stealing and eating pets. >> you have that kind of microphone in front of you, you really ought to understand at a very deep level how much your words have meaning. >> reporter: on wednesday, harris will be back in michigan where she and trump are neck and neck in the latest cbs news poll. both campaigns are working to win the crucial votes of union workers across the state. skyler henry, cbs news, washington. and cbs news will host the only vice presidential debate between senator j.d. vance and governor tim walz on tuesday, october 1st, right here in new york. you can catch our live coverage on cbs and streaming on cbs news 24/7 and paramount plus. when cbs news roundup continues, we'll get to the heart of the charges against sean "diddy" combs in a conversation with our expert entertainment analyst.

november accusing him of a long list of crimes, assault, rape, the list goes on from there. they settle within 24 hours for an undisclosed amount, but it opens up the floodgates for more victims to come out and tell stories against diddy to similar crimes as well. it leads to raids at his home in l.a. and miami. he continues to deny. he goes on instagram and says people are looking for a payday. enough is enough. says he denies everythig. then a 2016 video comes to light of him brutally attacking and assaulting cassie in a hotel lobby, and then he finally acknowledges, that which leads to more victims coming forward with their story, and here we are today. >> about those raids you mentioned, there was one in los angeles, one in miami. and i wonder what we learned, because prosecutors are now saying what they found. >> yeah, i mean, some of the most shocking things i think are the ar-15s, the guns. things that fueled these things they're calling freak parties or

something like that. so there is a lot of jobs which corroborate the sex trafficking pieces of the allegations. so a lot of things that corroborate the charges that are against him. >> okay. and in terms of what we're hearing from his team, what are his representatives saying about this? >> they're maintaining his innocence saying he'll continue to fight, he is a fighter, but the proof is out there. it's very public. it corroborates all the stories we're hearing and seeing out there. >> okay. and what about within the music industry? are people coming to his defense? what are we hearing? >> we're not hearing very much. people aren't really coming to his defense. and i think that's what's kind of concerning in a few different ways because he is so connected to so many other entertainers in the industry, i think a lot of fans are concerned about their beloved and prominent celebrities who are connected to him in any kind of a way, if they may get tied up in this at all. >> and these are such serious allegations, lamar. how are some music fans responding? >> well, of course the internet being the internet, of course there is the memes and there is the jokes, but there is also serious discourse about supporting the victims throughout this conversation and how they're getting dragged

through this and what that can mean for them throughout this core process. so there is that. but also, a lot of fans are talking about the stories that have been talked about for years within entertainment circles such as like diddy blowing up kid cuddy's car, and that's now being corroborated through these lawsuits coming to light. we're seeing a lot of the stories taking place. >> interesting. and what happens next in this case? >> we wait. diddy is still behind bars and we're going to have to wait for his day in court. >> and he will stay there because until his trial, that is, because he was not let out on bail today. >> correct. >> okay. lamar dawson, thank you so much. >> my pleasure. >> and stay with us. straight ahead on "cbs news roundup," the fed is expected to cut interest rate, but what does this really mean for perspective home buyers? we'll explain. stay with us.
