TEHRAN — Iranians chanted ‘‘Death to America’’ and burned the US flag after weekly prayers in Tehran on Friday despite their new president’s outreach to the West and promises of moderation and easing of tensions with the outside world.
The chants, customary after Friday services in the Iranian capital, reflect the challenges facing President Hassan Rouhani as he tries to build on the groundbreaking exchanges with Washington that included a telephone chat last week with President Obama — a gesture aimed at ending three decades of estrangement between the two countries.
Rouhani’s overtures have been hailed by both Iranian reformists and the country’s conservative clerical leadership.
But a wide array of Iranian hard-liners opposes any improved contact with the United States.
Diplomatic relations between the two were cut after the 1979 Islamic Revolution and the storming of the US Embassy in Tehran, when militants held 52 Americans hostage for 444 days.
During prayers Friday in Tehran, the master of ceremonies led the crowd into chants of ‘‘Death to America’’ at least twice from the podium.
The chant was then repeated several times by a group of worshipers who rallied after the ceremony, burning the American and Israeli flags, as they do almost every week.
However, Ayatollah Kazem Sedighi, a cleric who led the prayers, tried to strike middle ground, saying that America and Iran should ‘‘join hands’’ in a struggle to overcome sanctions that have crippled Iran’s economy.
Sedighi criticized Washington over the threat of new punitive measures against Iran and urged Obama to ‘‘come and work with’’ Rouhani in lifting the sanctions, which the cleric said had hurt not only people in Iran but also in the wider region, the United States, and Europe.
Though Sedighi said Iran would not pull back from its ‘‘peaceful nuclear rights,’’ he expressed hope that Rouhani’s policies would ‘‘save the region and the world from a dead end and a crisis.’’
Iran has faced repeated rounds of UN sanctions over its disputed nuclear program, which the West suspects is geared toward producing an atomic weapon.
The country is also living under tough US-led oil and banking sanctions that have slashed oil exports by half and shut Tehran out of the international financial system.
Tehran denies it wants nuclear weapons, insisting its nuclear activities are only for peaceful purposes such as power generation and cancer treatment.
In a visit to New York for the UN General Assembly last week, Rouhani agreed to restart nuclear talks with the five permanent members of the Security Council plus Germany in Geneva later this month.
During prayers Friday, the master of ceremonies led the crowd into chants of “Death to America” at least twice from the podium.
Another speaker on Friday, Mohammad Hossein Saffar Harandi, who is part of an advisory council to the Supreme Leader Ayatollah Ali Khamenei, said the United States decided to work things out with Iran through diplomacy because of the crisis it faces over Syria’s conflict.
‘‘But, honestly, we also need them,’’ Harandi said, referring to Americans. ‘‘We would like to have an opening that would remove these oppressive sanctions.’’
When the crowd erupted into another ‘‘Death to America’’ chant, Harandi said: ‘‘I did not raise that slogan that you are chanting.’’
