Former Israeli President and Prime Minister Shimon Peres underwent an operation Monday morning to have a pacemaker device implanted to prevent irregular heartbeats in the nonagenarian.

Staff from the former President’s office stated that the operation was undertaken after the 93-year old former Labor leader had returned to Israel, following a political conference in Italy.

The operation took place at Tel HaShomer Hospital in Ramat Gan. Peres is expected to be released from the hospital Tuesday morning.

Sources close to the former President say that Peres’ physicians had advised him to get the pacemaker device to prevent heart disorders.
