The situation in Cusco, Peru remains difficult  because the rains have not ceased. However, that is not the only problem the region faces. Amid allegations and rumors [es]  that tourists [es] were charged money in order to be rescued , which is something that the authorities have denied [es] , the Chilean government sent a Hercules aircraft [es]  on January 21 to pick up Chilean citizens. There are photos of those rescued here .
Other reports have surfaced in regards to rising food prices [es]  in the area of Aguas Calientes, the gateway town to Machu Picchu. The Attorney General ordered an investigation [es]  to verify and act if it finds price speculation in the restaurants and stores.
As expected, the news soon appeared about the complaints about a lack of transparency [es]  in the distribution of aid to victims. Many are hoping that the government addresses this issue.
In addition, there are concerns about the tourists who were hiking the Inca Trail  and in the Sacred Valley, when the landslides started. It is estimated that at the time, there were about 1,500 tourists in the area [es] , but to date it is not known whether all are safe. The total number of tourists in and around Machu Picchu was estimated to be 2,000.
Twitterers have been posting information on what has been happening in and around Cusco. Some of the tweets show the two sides of humanity:
