Prague - Former Czech president and playwright Vaclav Havel, an icon of anti-communist resistance, has been treated in a Prague hospital with "an inflammatory illness," his office said Tuesday.
Havel underwent an operation at hospital's otorhinolaryngology clinic, hospital spokeswoman Eva Jurinova said. She said his condition was "stabilized, nevertheless serious."
Neither the hospital, to which Havel was admitted Monday, nor Havel's office would provide further details.
