(CNN) -- Sudanese President Omar al-Bashir arrived in neighboring South Sudan on Monday for talks on unrest in the latter nation that has left hundreds dead. He flew into the airport in the capital of Juba before heading to the presidential palace to meet his South Sudan counterpart, President Salva Kiir. The two later held a joint news conference with al-Bashir stressing readiness to support South Sudan, according to the official Sudan News Agency. Al-Bashir's visit comes as rival parties in the South Sudan power struggle work to find a solution to the violence. Meanwhile, talks between South Sudan's government and rebels began Monday in Addis Ababa, Ethiopia. Those negotiations were delayed last week. "The two delegations appreciated the gravity of the situation and the need and urgency of resolving the crisis in South Sudan. They reminded themselves of the long-drawn liberation struggle that culminated in the independence of their country. They regretted the unfortunate situation which the current conflict has brought," read a statement from the Intergovernmental Authority on Development, an East African trade bloc helping to mediate between the parties. Talks are expected to pick up again on Tuesday. The negotiations "come not a moment too soon," African Union Chairwoman Nkosazana Dlamini-Zuma said in a statement. "Not a single day can be lost in the search for peace in South Sudan. Stopping the fighting in South Sudan is not only a humanitarian imperative but also a strategic necessity, in order to halt the rapid descent of Africa's newest nation into collapse." South Sudan erupted in violence on December 15 when rebels loyal to ousted Vice President Riek Machar tried to stage a coup. Since then, militia members loyal to the ousted leader have battled government forces. Violence quickly spread with reports of mass killings emerging nationwide. As teams from both sides are negotiating, fighting rages. Three weeks of fighting have left more than 1,000 people dead and forced 200,000 from their homes, officials say. South Sudan seceded from Sudan in 2011 after decades of war, making it the world's youngest nation. Despite the split, al-Bashir has a stake in the talks. Though South Sudan and Sudan divorced, they still have unresolved oil issues. Prolonged fighting has cut South Sudan's oil output, affecting both economies.

(CNN) -- Even a presidential campaign's airplane troubles can get partisan in an election year. Aviation incidents involving President Barack Obama and Ann Romney, wife of Republican presidential candidate Mitt Romney, have inspired hundreds of supporters commenting at CNN.com to connect those events to the candidates' political positions. When the Air Force One pilot aborted his first landing in Toledo, Ohio, due to weather on Wednesday, commenters were quick to jump on Obama. "See, Barack Obama can't even land a plane correctly," wrote a commenter whose handle is TheOtherBob. "He was probably checking the polls - thinks he has Ohio in the bag - no need to land," wrote another commenter. "He was distracted, since he was busy adjusting gas prices over his smart phone," wrote another commenter. Ann Romney's smoke-filled plane . Ann Romney couldn't catch a break, either. Her airplane cabin filling up with smoke due to an electrical problem was no laughing matter, but commenters quickly took aim at her husband and his response. Mitt Romney talked about not being able to open the airplane's windows in flight. (New York Times writer Ashley Parker, who wrote the presidential pool report mentioning the comments, declined to comment on his remarks, referring CNN to a New York magazine piece where she made it clear that Romney was joking.) "Maybe if Romney hadn't started the outsourcing trend, that plane would have been built and maintained better by hardworking 47%ers," wrote one commenter. "Firefighters came to the rescue, paramedics were there on time and the police took special care of your security. We are the 47% your husband scorns," wrote commenter Kweso. Reminders of the actual flying conditions . Enough with the political bickering, suggested some commenters. "The hate thrown out at the Romneys (and at President Obama) is just plain absurd," wrote commenter jolivier23. On Romney's flight: "CAN YOU PEOPLE STOP WITH THIS CHARADE. Can you just be happy that the everyone was safe and no one was injured," wrote one commenter. "What is wrong with you people? Why are you making this a political issue? I am just glad nobody was hurt. " On Obama's flight: "This incident with the President was just routine turbulence which is something that you really can't do anything about in the first place," wrote one commenter. "If the one of the best pilots (and co-pilots) in the U.S. Air Force aborts a landing you know the conditions were hairy," wrote daehttub2000. Perhaps remembering a line from that esteemed television show "Hill Street Blues," he wrote, "Let's be careful out there." Many of us have stories of grabbing a complete stranger or picking airline pretzels out of our hair after a particularly bad bout of turbulence. Do you have any stories to share?

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.
