PROBLEM: Robert, Louisiana (CNN) -- Three attempts to pump mud and 16 tries to stuff solid material into a breached Gulf of Mexico oil well failed to stop the flow, top BP executives said Saturday, and engineers and executives with the oil giant have decided to "move on to the next option." That option: Place a custom-built cap to fit over the "lower marine riser package," BP chief operation officer Doug Suttles said. BP crews were already at work Saturday to ready the materials for that option, he said. Suttles said three separate pumping efforts and 30,000 barrels of mud -- along with what chief executive officer Tony Hayward described as "16 different bridging material shots" -- just didn't do the trick. "We have not been able to stop the flow," a somber Suttles told reporters. " ... Repeated pumping, we don't believe, will achieve success, so we will move on to the next option." Suttles and other officials said that the "top kill" attempt to stop the flow did so -- but only as long as they were pumping. When the pumping stopped, the oil resumed its escape. And Coast Guard Rear Adm. Mary Landry said that BP would resume using undersea dispersants for the new attempt to trap the oil. Suttles said the lower marine riser package cap "should be able to capture most of the oil" that has fed what is now the largest oil spill in U.S. history, but he cautioned that the new cap will not provide a "tight mechanical seal." "We're confident the job will work, but obviously we cannot guarantee success at this time," he said. Engineers should be ready in about four to seven days to make the fresh attempt, he said. Landry said officials were "disappointed in today's announcement," but noted that the immediate efforts to stop the flow were never intended to be permanent. "The real solution, the end state, is a relief well," she said. BP currently is working on two relief wells, but they are not expected to be ready until August, Suttles said. Earlier, Suttles said that BP engineers would try to place a second blowout preventer -- the piece of equipment that failed when the Deepwater Horizon exploded on April 20 -- should the lower marine riser package fail. The failed blowout preventer is a 48-foot-tall, 450-ton apparatus that sits atop the well 5,000 feet underwater. Suttles and Landry praised the clean-up efforts, however, in light of the failure of the "top kill" attempt to stop the flow. "It's a tribute to everybody that we only have 107 miles of shoreline oiled and only 32 acres of marsh," Landry said. Meanwhile, teams in Louisiana were working Saturday on a clean-up project aimed at protecting coastal marshes. Plaquemines Parish President Billy Nungesser has said that machines would suck oil out of marshes Saturday after crews determined where to deploy them. But Nungesser told CNN that BP needed to "step up to the plate tonight to save our wetlands" by using its might to create sand barriers to prevent the oil from moving into the marshes. "BP needs to say it will pay to move those dredges and pump that sand berm," he said. "We are gonna die a slow death if we don't get that berm. We've got to have that barrier island." President Barack Obama, who toured the area Friday, said federal officials were prepared to authorize moving forward with "a portion of" an idea proposed by local officials, who want the Army Corps of Engineers to build a "sand boom" offshore to keep the water from getting into the fragile marshlands. But Nungesser said the marshes couldn't wait and that the effort needed to start immediately to save the Louisiana wetlands. Government scientists on Thursday said as many as 19,000 barrels (798,000 gallons) of oil were spewing into the ocean every day, making this disaster perhaps twice the size of the Exxon Valdez incident. Previously, BP officials and government scientists had said 5,000 barrels (210,000 gallons) of crude were flowing out daily. "This is clearly an environmental catastrophe," Hayward said Friday. "There's no two ways about it." In an e-mail message sent out after the announcement Saturday, Hayward said he was "disappointed that this operation didn't work." "The team executed the operation perfectly, and the technology worked without a single hitch," he said. "We remain committed to doing everything we can to make this situation right." Obama's visit to the region came under intense political pressure to take control of the situation. "We want to stop the leak, we want to contain and clean up the oil and we want to help the people in this region return to their lives and livelihoods as soon as possible," the president told reporters. About 25 percent of the Gulf of Mexico exclusive economic zone has been put off limits, according to the National Oceanic and Atmospheric Administration, and fishermen are worried the gushing oil will take a more serious toll than Hurricane Katrina did in 2005. "Katrina was nothing but rain, water and wind. This is poison. It's gas," oysterman Arthur Etienne said. CNN's Anderson Cooper contributed to this report.

PROBLEM: NEW YORK (CNN) -- Defense and diplomacy were on full display when the United Nations secretary-general took to the soccer field in the first U.N. '"DiploMatch." "It is very hard at my age to play soccer," said the 64-year-old Ban Ki-moon. Typically, a Saturday evening soccer game with mostly middle-aged men wouldn't garner much attention, unless an ambulance is required. But the recent match played between two modest teams of U.N. ambassadors and officials, along with Secretary-General Ban Ki-moon, was certainly not typical. The mood was competitive yet congenial as the dignitaries traded their suits for shorts and hit the soccer field at Chelsea Piers on a balmy New York evening April 25. "Soccer is a sport that really can unite the people and generate enormous power and energy among people regardless of where you are coming from," Ban said. "When you follow the balls, you just forget, and you become one team, and you become one nation. This is what we aim to achieve today." There was, of course, an underlying purpose behind the motivation to hit the pitch: support for a new charitable organization dedicated to advancing peace through the global reach and unifying power of soccer (also called football).  Watch Ban Ki-moon mix it up with diplomats on soccer field » . British U.N. Ambassador John Sawers summed up the rationale motivating the event. "Soccer's the great world game, and this is [the] United Nations, the great world organization, playing it for charity, so it's a lot of fun." "Football for reconciliation" is the driving purpose of Play31, the organization behind the U.N. game. The group says the sport has the unique potential "to bring people together, spread joy and to create healing in post-conflict societies." Its mission statement further explains, "By donating footballs and facilitating community gatherings, we contribute to the creation of peaceful societies where children can exercise their right to play." Play31 and "the right to play" are derived from Article 31 of the United Nations Convention on the Rights of the Child. The 1989 summit sought to guarantee certain universal rights for children under 18, including "the right of the child to rest and leisure, to engage in play and recreational activities appropriate to the age of the child and to participate freely in cultural life and the arts." Jakob Lund, the 26-year-old founder and president of Play31, was inspired to launch his program after spending time in Sierra Leone, a nation ravaged by 11 years of civil strife. "We use soccer as a facilitator for people meeting each other and for people simply just interacting ... and I think that is something true for football is that it can transcend borders, languages, races, everything that we see can normally divide people -- on the football field, it can unite them, and that's what is so special." Added the enthusiastic U.N. ambassador from Paraguay, Eladio Loizaga, who contributed two goals in the first half for his team: "I mean, I didn't expect that! Two goals! I tried to put my best tonight for the children and for the event." Radhika Coomaraswamy, special representative for children in armed conflict, said, "there is really something to do with children that really brings the United Nations together." Ban also emphasized the plight of children as an important priority on the U.N. agenda. "This is a very small symbolic event, but though it may be small, this will, I hope, demonstrate our solidarity to those people, many young children, who are in war-torn countries, who really want some hope from the international community. I hope this will help." But even with all the togetherness for a good cause, settling disputes on the pitch versus the halls of the United Nations had to have been a different experience for the ambassadors. Sawers explained, "these guys I spend my days from Monday to Friday negotiating with, and we have fun on weekends, so this is us having fun." Chile's Ambassador Heraldo Muñoz, one of the team captains, elaborated. "Getting out of the U.N. and of negotiations, and speeches ... is quite good. I think it should say something about humanity that we are not only diplomats, but we are also football players and poets and writers." The other team was led by Ambassador Christian Wenaweser of Liechtenstein. Wenaweser was quite impressed with one particular participant, expressing how he thought the secretary-general's performance was "amazing." "He gave up his right to rest for this, and I think it's amazing. And he played well; he had good positioning, good defense. It was great," Wenaweser said. Laughing, Ban responded to reactions about his defensive prowess. "When the ball comes to me, then I have to defend my team, so that was very, very difficult. But I think I have defended well." The 64 year-old secretary-general played nearly the entire game, mixing it up with fellow U.N. dignitaries. "It is very hard at my age to play soccer," Ban conceded. "It's very hard, but I feel very much a sense of full excitement and energy." Ban's dogged defense clearly made an impact. However, the secretary-general couldn't resist his role as the world's lead diplomat, even on the football field, and changed teams at halftime. Diplomatically, the score was not recorded, although observers said Team Lichtenstein was the victor. Ban played defense the entire time, except when he came off for a couple breathers. When he came off in the first half, the other team quickly scored three goals.

PROBLEM: (CNN) -- Veteran striker Raul Gonzalez scored his 71st Champions League goal to help Schalke beat holders Inter Milan 2-1 on the night and 7-3 on aggregate to reach the semifinals of the competition on Wednesday. Already in the driving seat after their stunning 5-2 first leg win at the San Siro, the German Bundesliga side never looked likely to relinquish their advantage and eased through to the last four, where they will now face Manchester United. Raul opened the scoring on the stroke of half-time, controlling an inch-perfect pass from compatriot Jose Manuel Jurado, before rounding goalkeeper Julio Cesar to slip the ball home. However, the Italian side levelled the scores just four minutes later when Thiago Motta was left unmarked from a corner to head home. Benedikt Hoewedes then had a header ruled out for offside, but the Schalke defender was not to be denied and he hit the winner with nine minutes remaining, firing home after latching onto Raul's pass. Schalke coach Ralf Rangnick told reporters: "We have produced two great performances against Inter. "If you only allow the Champions League winners a couple of chances, you know you have played well. "Each player worked hard for each other and that was the key to our success," he added. Schalke will host United in Gelsenkirchen on April 26 in the first leg, with the return at Old Trafford on May 4.
