"We call on Iran to restore full cooperation with the agency and fully implement its obligations," said EU foreign policy spokesman Anouar El Anouni, as regional tensions flared ahead of weekend nuclear talks between Washington and Tehran.
"We call on Iran to show restraint and avoid any step that would further escalate the situation," he added, in reference to Iran's promise to "significantly" increase enrichment activities.
Meanwhile, Paris denounced Iran's "deliberate pursuit of nuclear escalation," urging Tehran to return to the negotiating table, a French foreign ministry spokesman said.
Tehran's announcement to ramp up enrichment came after the UN nuclear watchdog accused Iran of non-compliance with its obligations, prompting Israel to say the world must respond "decisively".
The United States, Israel and other Western countries have repeatedly accused Iran of seeking a nuclear weapon, an accusation Tehran has categorically denied.
