Israeli Prime Minister Benjamin Netanyahu accused Iran on Thursday of maintaining a secret nuclear weapons storage facility in Tehran.
"Iran has not abandoned its goal to develop nuclear weapons," Netanyahu told the U.N. General Assembly as he held up maps and photos of a building in Tehran's Turquzabad district.
Netanyahu said Iran uses the building to store "massive amounts of equipment and material from Iran's secret weapons program."
He said he'd informed the International Atomic Energy Agency and some intelligence agencies about the facility and had demanded that the IAEA immediately inspect it.
Iranian Foreign Minister Mohammad Javad Zarif rejected Netanyahu's presentation as an "arts and crafts show." Iran has routinely denied it has a nuclear weapons development program.
"The only purpose of this is to undercut the reality that Israel is the biggest threat to the region,'' Zarif said.
Speaking to reporters at the assembly Wednesday, U.S. President Donald Trump defended his decision to withdraw from the 2015 six-nation agreement for Tehran to give up its nuclear program in exchange for the removal of crippling economic sanctions.
Trump said "Iran has to come back and they have to talk" if it wants to avoid a new round of economic sanctions.
