Israel's Prime Minister Benjamin Netanyahu said that Israel does not conduct espionage against the US, Iran and other countries.
"These allegations are utterly false. Israel does not conduct espionage against the United States or Israel's other allies. The false allegations are clearly intended to undermine the strong ties between the United States and Israel and the security and intelligence relationship we share," CNN channel cited him as saying.
Earlier in the day, the Wall Street Journal reported, citing US officials, that Israel was spying on the international talks on the Iran's nuclear program, in an effort to infiltrate the negotiations and hinder any potential deal.
According to the newspaper, Israel had received additional information from confidential US briefings, informants and diplomatic contacts in Europe, RIA Novosti reports.
