Paragraph: In the interview, Bolsonaro also stuck to the government’s assertion that a Greek freighter caused the oil spill scattered across beaches along 1,300 miles (2,100 kilometers) of coastline even after the shipowner’s denial of any leakage from its vessel. “All signs point to this Greek cargo ship. All of them,” he told Record TV, adding that the leak, “by all accounts looks like it was criminal.” Brazil’s government has been striving to investigate the cause of the spill that has hit 321 beaches along the northeast coast since early September, hurting fishing and tourism. Authorities have described the spill as one of the country’s worst environmental disasters. The crude’s density renders it invisible from above, making it hard to track its origin or to have a clear picture of the amount of oil yet to reach Brazil’s coast. Some 4,000 tons of oil has been collected from northeastern beaches thus far, according to a statement Sunday from the Navy, Brazil’s environmental regulator, and the national petroleum agency. “To say how much oil there still is very difficult to say,” Commander Leonardo Puntel of the Brazilian Navy said at a press conference on Monday. “Since the oil is underwater, we don’t know if there’s still a lot or a little. There is effectively no correct and accurate way to monitor these oil spots,” he said, adding that they have seen a decrease in oil arriving onto beaches in recent days. He called the disaster “unprecedented.” “There is no case in the world of a large-scale oil spill where the origins are totally unknown. This case has no parallel, we don’t know who polluter is,” Puntel said. Brazil’s defense minister, Gen. Fernando Azevedo e Silva, also stressed how challenging it is to calculate the spill’s scope. “It is not detectable by satellite. ... It is imperceptible. We do not know how much will still come,” he said. David Zee, an oceanographer at the State University of Rio de Janeiro, said that the 4,000 tons of collected oil is “just the tip of the iceberg,” both because the cleanup effort is mostly limited to sandy beaches in populated areas and also because a large portion of spilled oil is likely spread deep beneath the ocean’s surface. Furthermore, when currents bring oil to sandy shores, it is relatively easy to collect, while is nearly impossible to remove from corals and mangrove forests, which make up part of the affected area, Zee said. Brazilian prosecutors have named Greek shipping company Delta Tankers Ltd as a suspect of the leak’s origins. The company issued a statement earlier saying it found no evidence of leakage after reviewing the ship’s cameras and sensors. “This material will be willingly shared with Brazilian authorities, should they contact the company regarding this investigation. So far, no such contact has been made,” the statement said. Federal Police officer Franco Perazzoni said at Monday’s press conference that the company will be officially notified via Interpol. Brazilian prosecutors said previously that Delta’s oil tanker, named Bouboulina, was navigating through Brazilian waters at the time and location of the spill. The ship was carrying oil from Venezuela to Malaysia. In a search order seen Friday by The Associated Press, Brazilian prosecutors said “there is no indication of another boat” that could have discharged the Venezuelan crude into the sea. Brazilian armed forces along with environmental protection agencies and petroleum authorities are leading an operation to clean, monitor and investigate the oil spill. Several public universities are conducting research about the spill’s origins and impact. Television footage has also shown volunteers flocking to beaches to help with the cleanup, often without government supervision. Of particular concern at the moment is the Abrolhos national marine park, home to Brazil’s largest coral reefs. Authorities said Sunday night that they had removed the fragments of oil that had appeared in the park and so far no new traces had been found. “A very small amount of oil arrived on November 2, on November 3 only a few fragments remained, today there’s none,” Puntel said in the Monday press conference. “Will more oil fragments come? Maybe.” Claim: Brazil reckons with new oil spill mystery: When will it end?.
Brazilian authorities said on Monday that they have no way of knowing how much more oil will wash ashore the country’s northeastern coast, despite President Jair Bolsonaro’s ominous warning during a Sunday night TV interview that “the worst is yet to come.”

Paragraph: Three of the other five patients are in either a serious or a critical condition in hospital, while the remaining two have mild symptoms, the United Nations health agency said in a disease outbreak update. H7N9 bird flu emerged last year in China and has infected around 150 people so far there and in Taiwan and Hong Kong, killing at least 46 of them. The latest death was a 38-year-old man from China’s Fujian Province who became ill with H7N9 on January 3, was admitted to hospital on January 8 but died 2 days later. He had underlying illnesses, including tuberculosis and pneumoconiosis. China’s state news agency Xinhua reported another death from H7N9 in the southwestern Guizhou province on Monday, but this has yet to be confirmed by the WHO. A 65-year-old man infected with H7N9 also died in Hong Kong, the government said on Monday. The WHO reiterated there is no evidence as yet of any easy or sustained person-to-person transmission of the strain, and that the source of the human infections is still under investigation. Researchers in the United States said last month that while it is not impossible that H7N9 could become easily transmissible between people, it would need to undergo multiple mutations to do that. Scientists around the world are keeping a watchful eye, on alert for any sign the virus might develop that potential and start to spread rapidly. Claim: Death toll from new China bird flu rises: WHO.
Six more people in China have been confirmed as infected with the new H7N9 strain of bird flu and one of them has died, the World Health Organisation (WHO) said on Monday.

Paragraph: Berina Hamidovic was the first victim of politicking over identity numbers, which has united Bosnians in protests against the institutional paralysis that has blocked post-conflict reforms and the country’s path towards the European Union. The somber gathering followed days of protests in Sarajevo and other towns over lawmakers’ failure to agree new legislation on citizens’ identity numbers. The row has left babies born since February unregistered, and therefore denied passports or medical cards. The protesters this time did not carry banners or posters, but encircled parliament with a ring of candles placed on the ground, and stood or walked in silence. The baby’s parents said the time they had wasted persuading Serbian border police to let her in without a passport to go to a hospital in Belgrade for surgery had cost her her chance of life. The baby was diagnosed with tracheoesophageal fistula - a hole between her gullet and windpipe - and had already had an unsuccessful operation in Sarajevo. “We practically had to take the child across the border illegally, although she was legally allowed to travel for urgent health reasons,” the baby’s father Emir Hamidovic said. When the baby was finally admitted to hospital in Belgrade, Bosnian authorities refused to pay for the surgery. Though the Serbian doctors agreed to carry out the procedure, the baby contracted an infection and died. “She perhaps had a chance to stay alive, but this is an obvious example how the state does not take care of its citizens,” said Hamidovic, 31, who is unemployed. The protests over ID numbers started two weeks ago after another 3-month-old baby was unable to leave for urgent surgery abroad because lawmakers could not agree how to redraw the districts that determine the 13-digit identification number assigned to each citizen. Similar ethnic wrangles have plagued Bosnia since the end of its 1992-95 war, which left it divided along ethnic lines with a weak central government and a system of ethnic quotas that has stifled development. The Serbs are pressing for a new registration arrangement along territorial lines. Muslims, known as Bosniaks, say that would only cement the ethnic divide. Claim: Bosnians mourn baby who died for lack of ID number.

Thousands of Bosnians gathered in front of parliament on Sunday evening to mourn a three-month-old baby who died after failing to get timely surgery because a parliamentary wrangle prevented her getting a passport.
