Iran’s intelligence minister claimed without offering evidence Sunday that Tehran seized an “important treasury” of information regarding Israel’s nuclear program, ahead of a week in which the Islamic Republic likely will face new diplomatic pressure over its own program.

Israel, widely believed to be the only nuclear-armed state in the Middle East, has long considered Iran’s nuclear ambitions a direct national security threat. Prime Minister Benjamin Netanyahu has repeatedly stated that Israel would be prepared to use military force to prevent Iran from becoming a nuclear weapons power.
