VIENNA (AP) — Iran has further increased its stockpile of uranium enriched to near weapons-grade levels, according to a confidential report on Monday by the United Nations’ nuclear watchdog, the latest in Tehran’s attempts to steadily exert pressure on the international community.

Iran is seeking to have economic sanctions imposed over the country’s controversial nuclear program lifted in exchange for slowing the program down. The program — as all matters of state in Iran — are under the guidance of Iran’s supreme leader, Ayatollah Ali Khamenei, and that likely won’t change in the wake of last week’s helicopter crash that killed Iran’s president and foreign minister.

The report by the International Atomic Energy Agency also comes against the backdrop of heightened tensions in the wider Middle East over the ongoing Israel-Hamas war. Israel and Iran have carried out direct strikes on each other’s territory for the first time last month.
