the, the, this is dw news live from berlin, social media, boss's face, a grilling at the us congress. senators choose, choose the head of facebook and other companies, not doing enough to protect children online. plus, israel floods come off tunnel and gaza. the army says it's pumping the water into the vest network, despite warnings of jeopardizes drinking water from millions of palestinians the i'm on the in the so thanks for joining us. the world's top tech ceos have faced

growing from us lawmakers and washington, members of the senate judiciary committee accuse social media giants like tick tock, x, discord, snap, and mehta, of not doing enough to protect children and teens on their platforms of met. a chief marks was dr. burke, unfortunately is facebook and instagram. i want to give a public apology and announced a new child protection measures loved one. you also told law makers that social media is quote, on balance family, not harmful to young people's mental health. all that drew a heated exchange between the sucker bird and republican senator josh holly. let's have a look. it said you mischaracterized 37 percent of teenage girls between $13.15. were exposed to unwanted nudity in a week on instagram and you knew about it. who did you buy or senator? this is why we're building all. what did you firewalls? a center that's. i don't think that that's who did you fired? i'm not gonna answer that is this is i or anybody, right? you didn't take any significant because it's appropriate to talk about it,

but it's not a part of the decisions that and parents so you didn't take any action. you didn't take any action or didn't fire anybody. you haven't complicated. i think let me ask you this, let me ask you this. there's families of victims here today. have you apologize to the victims? i would you like to do so now? well, they're here. you're on national television, would you like now to apologize to the victims who have been harmed, but you're not showing the pictures. would you like to apologize for what you've done to these good people 1st. okay, dw is benjamin alvarez gruber was following those hearings in washington. i asked him why mark secretary was facing so much heat from us lawmakers to this,

right. indeed, it was a heated exchange. the race, growing frustration also disappointment because the issue of online child safety is not new. and many i say that the companies on social media companies are not doing enough. and that's also what the senator's is said to day. one of them even said that the fact that no new bills on child safety has been passed is exactly due to the power that the social media companies half of the companies, the senators accused of not only doing enough, but also the actively blocking steps to hold it'd be social media a company's accountable. so this definitely disappointed this appointment in this hearing and not only by the members of the family of the victims of online explanation, but also from the centers across the. 1 there are 2 suckers of having, and i quote, a product that is killing people. so the moment that we just saw her that was highly emotional, highly, also surprising when max talk about turned it to the audience,

apologize to the family. that was definitely one of the most unusual parts of the hearing because they were to proceed with them in the lifestream and parents were holding a pictures of, of the kids that were also a victims of abuse on the social media. so a moment definitely that we will remember for a long time, but the bigger question came directly afterwards. and when he was ask why the company and you should be sued personally for that not just the company, but he himself knew dodge the question. and also he dosh the question whether was a suggestion of a senator to set up a victims compensation fund can almost see the sweat breaking out on his brow. there i'm so besides that exchange, what stood out to you about this hearing what definitely stood out here is that this by partisan support. so this greeting as we call this senate hearings, a part of an effort to pass legislation after years of an action by congress and during the many different exchanges between several centers and some a, c,

e o 's or was this common line that there is support from both republicans and also from democrats to increase child safety regulations for social media sites. there is broad consensus and many of the most things that the promises and the pleasures of protecting children online is not enough and that impunity also is over some center. there's also even question is the 2nd best opening statement to deny that there's even a link between using social media and young people and there it was in the mental health. so that's something that contradicts the company's own research. so now the important step will be what will the next steps will be in congress to better protect children online? that's a good question. we'll have to watch out for that benjamin others gruber in washington dc. thank you. and turning to the middle east now is real, has confirmed that it's forces have been pumping sea water into how mos tunnels under garza is really army says that it's ensuring the ground water supplies are

not effected after experts. one that flooding the vast network to permanently damaged the drinking water for girls is 2300000 residents. critics also so the tactic could endanger the remaining hostages, held by him off since the october 7th terror attacks. well, mike martin is a former british army officer and senior fellow at the department of worst studies, a king's college london. he gave us more details about israel's flooding operation . it's a, it's, it's actually very simple. any fire department of any town will have the fire hydrants, the pumps that are able to take the c will. it's obviously garza is on the coast. so there's not limited supply of water. you lay a pipe out to sea with boys. you get a pump and then you stick it into the nearest entrance, the tunnel. many of these tunnels are linked up. so if you fill out one segment, it will overflow and spill into the next segment. and as water levels rise of sleep,

both will sink down to the fed up the both. remember the tunnel fuss as it rises, people chops and supposedly the die. oh, they will have to come to the surface which silver see what's the idea these when he defense schools is one. i think the problem is that israel has defined 2 will rooms and they all to destroy thomas and to get the whole seas out. and it's very difficult to do one without impacting on the other. so this really is the perfect example of that. so as you fill these tunnels and we can speak about whether it's an effective military tax, it can be that should flash most people out. the problem is, of course, that most of the hostages, how much is keeping all of a sudden you're going to be in the tunnels and they going to be quite deep down in the tunnel system cuz thomas wants them to stay alive. and so is vital is achieving one of his war objectives, but making it impossible to advise the officer, but she is more objective when it comes to getting the hostages back and now to
