The presidents of both Nicaragua and Venezuela have indicated their countries could offer political asylum to US fugitive Edward Snowden. Venezuela’s Nicolas Maduro said it would give asylum to the intelligence leaker, who is believed to be holed up in a transit area of Moscow airport. Meanwhile Nicaraguan President Daniel Ortega said his country would do so “if circumstances permit”. Wikileaks said Mr Snowden had applied to six additional countries on Friday. The whistleblowing website said it would not name the countries “due to attempted US interference”. Mr Snowden has already asked 21 countries for asylum, most of whom have turned down his request. But even if a country accepted the American’s application, getting there could prove difficult, the BBC’s Steven Rosenberg, in Moscow, reports. European airspace could be closed to any aircraft suspected of carrying the fugitive, our correspondent says. Earlier this week, several European countries reportedly refused to allow the Bolivian president’s jet to cross their airspace on its way back from Moscow – apparently because of suspicions that Edward Snowden was on board.
