An Iranian general is saying that a purported Israeli drone shot down near a nuclear facility flew in from a northern country that one was part of the Soviet Union.

The semi-official Fars news agency quoted Gen. Masoud Jazayeri, the armed forces' deputy chief of staff, making the allegation Wednesday. It reported that Jazayeri said the country must make "compensatory actions" or else be publicly named.

There are three former Soviet republics north of Iran: Armenia, Azerbaijan and Turkmenistan.

On Saturday, Iran's powerful Revolutionary Guard said it shot down an Israeli drone near the country's uranium enrichment facility in Natanz, some 240 kilometers (150 miles) south of the capital, Tehran. State television aired footage of the purported drone Monday.

Israeli officials have not comment on the incident.
