Jerusalem (CNN) -- Israel has arrested an Iranian-born man, accusing him of spying for Tehran. He was carrying photos of various sites, including the U.S. Embassy in Tel Aviv, the Israeli government said Sunday. The announcement came as Israeli Prime Minister Benjamin Netanyahu traveled to the United States to address the United Nations General Assembly and meet with U.S. President Barack Obama. Netanyahu has been outspokenly wary of Iran's apparent efforts to improve relations with the West. "I will tell the truth in the face of the sweet talk and the onslaught of smiles," he said Saturday, in the wake of last week's speech at the U.N. by Iranian President Hassan Rouhani.
