EXPLAINER: Why Iran cracks down at home, cozies up to Moscow

DUBAI, United Arab Emirates (AP) — Backed into a corner by the West, Iran is ramping up uranium enrichment, clamping down on dissent over its worsening economy and deepening ties with Moscow. Russian President Vladimir Putin is heading to Tehran next week to meet with Iran’s leader, while U.S. President Joe Biden is in the Middle East, meeting with Iran’s foes. The White House alleges Tehran is preparing to send Russia armed drones for use in Ukraine. With pressure growing on Tehran, it has few options but to boost cooperation with Moscow, a historic rival. Talks to revive the 2015 nuclear deal, which eased sanctions on Iran in return for curbs on its atomic program, are at a standstill.
