Former Israeli Prime Minister Benjamin Netanyahu underwent tests after feeling ill during prayers on the Jewish Day of Atonement, his office said in a statement on Wednesday.
"Former Prime Minister Netanyahu felt unwell while praying at synagogue. He underwent a series of tests on site that came out normal and he now feels well," the statement said.
Netanyahu will undergo further checks at a hospital "to remove any doubt," it added.
The former premier, Israel's longest-serving prime minister, heads a bloc of right-wing and ultra-religious parties ahead of a general election on Nov. 1. He has vowed to make a comeback despite standing trial for corruption charges that he denies.
