Article: Edward Snowden--the fugitive former U.S.intelligence employee --appears to be stuck in Moscow, unable to leave without a valid American passport, according to interviews Sunday with two men who had sought to aid him: WikiLeaks' Julian Assange and Ecuadoran President Rafael Correa. Snowden, 30, arrived at Moscow's Sheremetyevo International Airport last weekend, after previously taking refuge in Hong Kong. Moscow was only supposed to be a stopover.WikiLeaks, the anti-secrecy organization, had said Snowden was headed on to Ecuador--whose president has been critical of the United States -- and that he would seek _ there. Now, however, both men said Snowden is unable to leave. "The United States, by canceling his passport, has left him for the moment trapped in Russia," said Assange, the founder of WikiLeaks, on ABC ' s " This Week With George Stephanopoulos". The United States canceled Snowden' s passport last weekend. Assange criticized the United States, saying: " To take a passport from a young man in a difficult situation like that is a disgusting action." President Correa spoke to the Associated Press in Puerto Viejo, Ecuador. For now, he told the AP, Snowden was "under the care of the Russian authorities. " "This is the decision of Russian authorities. He doesn't have a passport. I don't know the Russian laws, I don' t know if he can leave the airport, but I understand that he can' t," Correa said. He said that the case was now out of Ecuador' s hands. "If Snowden arrives at an Ecuadoran Embassy, we' 11 analyze his request for asylum." Snowden traveled from Hong Kong to Moscow on his U.S.passport. Although the U.S.had already revoked it, Hong Kong authorities said they hadn't received the official request to cancel the passport before Snowden left. An official at the Ecuadoran Embassy in London had also issued a letter of safe passage for Snowden. But Snowden apparently did not use it for his trip to Moscow. And it doesn't appear that the Ecuadoran government would make a similar gesture again. On... Question: Edward Snowden is a person who once worked in a federal department _ . Answer:

The plan was put forward after Gates came to London to watch the game between US teen player Ariel Hsing and Chinese Li Xiaoxia on Sunday, Sharara told Xinhua in an interview. Sharara didn't disclose the details, but said that Gates offered to help after watching Hsing's match, in which the 16-year-old girl nearly pulled off one of the biggest upsets in Olympic table tennis history, pushing No. 2 seed Li to the limit before losing 4-2 in six tight sets. "Gates was surprised to see the young American girl played so well. He asked me what he can do to help promote table tennis in the United States. I think we'll work with him.

If we give more chances to the top countries, someone like Hsing will not come to the Olympic Games. They have no chance. But if we give them the chance, we can see what they can do," Sharara said. Sharara said the change increased the pressure on strong teams, like China, Japan, South Korea and Germany. "But they understand now because they saw other NOCs attending. Some countries before had no chance to play in table tennis, but now they are joining in table tennis." Other changes made to the Olympic Games include the color of floor (from red to blue) and new table design.
