PRISTINA, Serbia and Montenegro (Reuters) - Kosovo President Ibrahim Rugova, the ethnic Albanian pro-independence leader undergoing medical tests in Germany, is "seriously ill," a senior foreign diplomat said on Wednesday.
The 60-year-old president was flown to a U.S. military hospital at Landstuhl in western Germany on Saturday after aides said his health had deteriorated following a bout of flu.
An official spokesman refused to comment on Rugova's condition. But a senior foreign diplomat told Reuters: "He is in very serious condition."
Rugova has been at the heart of Kosovo Albanian efforts to win independence from Serbia for the past 15 years.
The province became a de facto U.N. protectorate in 1999 after NATO bombing forced the withdrawal of Serb forces accused of atrocities in fighting separatist rebels.
There is no clear successor to Rugova, who has twice been elected president since the war.
