Apparently, this is the first case of human-to-human transmission of the bird flu virus. Experts from the World Health Organization, studying the circumstances of the death of two sisters in Vietnam, found that they most likely became infected from their brother. He died earlier and also had bird flu symptoms. Until now, it was believed that the virus was transmitted to people only from chickens and ducks. An outbreak of bird flu has been reported in a number of Asian countries. In China, doctors assure that they are able to take control of the situation. They refer to accumulated experience and specially developed technologies. Vaccination of healthy birds and destruction of sick birds is carried out. On Sunday there were two explosions in the Kurdish city of Erbil. The devices were detonated by suicide bombers at intervals of five minutes. The first terrorist attack was carried out at the office of the Kurdistan Democratic Party, the second at the headquarters of its rivals, the Patriotic Union of Kurdistan. At the time of the sabotage, the Muslim holiday of sacrifice was celebrated in the party offices. According to preliminary data, at least 56 people died. Among them are members of the city government. Saudi Arabia's annual Hajj ritual continues despite the tragedy that killed 244 people on Sunday. People died in Mina in a stampede during a ritual of stoning a column representing the devil. Most pilgrims were not frightened by the incident, since Muslims believe that dying on Hajj is a gift from Heaven that not everyone gets. Despite security measures that are increased during the pilgrimage, it ends in casualties every year. So, in 1990, one and a half thousand people died in a tunnel in Mecca.
