JERUSALEM (AFP) - Israeli ex-president and Nobel Peace Prize winner Shimon Peres was "fighting for his life" Tuesday (Sept 27) after a stroke suffered earlier this month, a source close to the veteran statesman said.
The downturn in the 93-year-old's condition came about two weeks after Israel's last remaining founding father's stroke that put the Jewish state on edge over his condition.
He has been hospitalised near Tel Aviv since Sept 13, when he was admitted to hospital feeling unwell and suffered the stroke while there.
He has been under sedation and respiratory support in intensive care.
"The president is fighting for his life," the source told AFP, speaking on condition of anonymity.
"His health position is very, very difficult. His doctors are worried about his health."
Peres has held nearly every major office in Israel, serving twice as prime minister. He was also president, a mostly ceremonial role, from 2007 to 2014.
He won the 1994 Nobel Peace Prize jointly with prime minister Yitzhak Rabin and Palestinian leader Yasser Arafat for his role in negotiating the Oslo Accords, which envisioned an independent Palestinian state.
The former hawk turned dove is widely respected both in Israel and abroad.
After suffering the stroke, he received an outpouring of support from across the world, including from Pope Francis, US President Barack Obama, the Clinton family, Donald Trump, Britain's ex-premier Tony Blair and Russian President Vladimir Putin.
UN Secretary General Ban Ki Moon has said he was hoping Peres made a "swift and full recovery", calling him "tireless in seeking peace between Israelis and Palestinians".
There had been signs of improvement last week.
On Sept 18, Peres's office said doctors planned to gradually reduce his sedation and respiratory support to judge his response.
His personal physician and son-in-law Rafi Walden had said at the time that Peres had seen "very slow, moderate improvement".
On Tuesday, Walden declined to comment in detail, saying only that his condition was "severe".
In January, Peres was hospitalised twice because of heart trouble.
In the first case, the hospital said he had suffered a "mild cardiac event" and underwent catheterisation to widen an artery.
He was rushed to hospital a second time just days later with chest pains and an irregular heartbeat.
Peres has sought to maintain an active schedule despite his age, particularly through events related to his Peres Center for Peace.
When leaving hospital on Jan 19, Peres said he was keen to get back to work.
"I'm so happy to return to work, that was the whole purpose of this operation," he said.
In March, he met British supermodel Naomi Campbell at his Peres Center for Peace during an event linked to International Women's Day. On the same day, he met visiting US Vice President Joe Biden.
Born in Poland in 1923, Peres emigrated to what was then British-mandated Palestine when he was 11.
He joined the Zionist struggle and met David Ben-Gurion, who would become his mentor and Israel's first prime minister.
Peres became director general of the nascent defence ministry at just 29 years old.
Beyond his accomplishments in the public eye, he was also seen as a driving force in the development of Israel's undeclared nuclear programme.
Peres once confided that the secret to his longevity was daily exercise, eating little and drinking one or two glasses of good wine.
