A spokeswoman for Israel's former President Shimon Peres says the 92-year-old is being rushed to hospital after experiencing chest pains.

Ayelet Frisch said medics treated him at his home Sunday night and detected a "light irregular heart rate." She said the doctors decided he should spend the night in hospital for observation.

Peres was discharged from hospital last week after suffering a mild heart attack.

Peres completed his seven-year term as president in 2014. He remains active through his non-governmental Peres Center for Peace, which promotes coexistence between Arabs and Jews.

In a seven-decade political career, Peres served three stints as prime minister.

Peres won the Nobel Peace Prize in 1994 following the signing of the Oslo peace accords with the Palestinians.
