Emergency talks have been initiated by the World Health Organization amid rising concern over polio.

WHO emergency meetings typically take the form of telephone conferences between experts and officials around the globe, steered from the agency's Geneva headquarters.
Polio, a crippling and potentially fatal viral disease that mainly affects children under the age of five, has come close to being beaten as the result of a 25-year effort.
The number of recorded cases worldwide has fallen from 350,000 in 1988 to 406 in 2013, according to WHO data.
Polio is currently endemic in three countries, Afghanistan, Nigeria and Pakistan, down from 125 in 1988.
"However, wild poliovirus continues to spread internationally from both endemic and re-infected countries," the WHO said.
