The European Union is urging Iran to stick by a deal that would limit its uranium enrichment.

EU leaders complain in a draft statement discussed at a summit on Friday about “Iran’s persistent failure to meet its international obligations.”

Tehran is considering a plan proposed last week at talks involving Iran, the U.S., Russia and France.

But a Western diplomat in Vienna said on Thursday that Tehran had rejected the plan, which calls for Iran to export most of its enriched uranium, offering instead to enrich it to a higher level inside the country under U.N. supervision.

In the statement, the EU leaders say they “deplore the continued violations of human rights in Iran” and urge Iran to release EU citizens and employees of European missions charged or held in Iran.
