Defense Secretary Saul Cutts denied reports of a rift between the prime minister and the military amid claims that Benjamin Netanyahu wanted to launch a ground attack on Iran before Tuesday's election.
The prime minister's office also dismissed news reports that Mr. Netanyahu unsuccessfully pressured President Trump to launch a new wave of strikes as fake.
Gadi Eisenkot, Mr. Netanyahu's main opponent, the former chief of staff, accused the prime minister of exaggerating the Iranian threat when it was politically expedient.
This dispute was described as an unprecedented confrontation between the Prime Minister and the Chief of Staff.
The polls show a close race between Netanyahu and the opposition bloc led by Gadi Eisenkot.
