Former Israeli Prime Minister Benjamin Netanyahu was hospitalized after he felt ill during prayers on the Jewish Day of Atonement, Reuters reported.
"Former Prime Minister Netanyahu felt ill while praying in a synagogue. He was given a series of tests on the spot, which turned out to be normal, and he now feels fine," his office said in a statement.
Netanyahu will undergo further tests at the hospital "to dispel any doubts."
The former Israeli prime minister is leading a bloc of right-wing and ultra-religious parties in the run-up to the Nov. 1 general election. He has vowed to return despite facing trial on corruption charges, which he denies.
