Pope Francis landed in Kazakhstan on Tuesday to attend an international religious gathering, as part of his three-day visit to the central Asian country.

In the Kazakh capital Nur-Sultan, which was called Astana until 2019, the so-called Congress of Leaders of World and Traditional Religions is taking place for the seventh time.

Francis is the first pope to attend the international meeting organized by the Kazakh government. Kazakh President Kassym-Jomart Tokayev deemed his presence an honour.

Until now, John Paul II had been the only pope to visit post-independence Kazakhstan, in 2001.

For the 85-year-old pope, who suffers from knee problems and spends most of his time in a wheelchair, it is his third trip abroad in 2022, following trips to Malta and Canada.

The pope described his trip as a “pilgrimage of dialogue and peace” as he addressed the faithful on Sunday.

The head of the Catholic Church landed in Nur-Sultan and was received by President Tokayev. Following the airport welcome, Francis attended a reception with the president and diplomats.

Upon his arrival, Francis stressed that his trip is in solidarity with all those seeking peace in the world. Calling himself a “pilgrim of peace,” Francis said he wishes to amplify the cries of those who advocate for peace around the world.

He addressed the war in Ukraine while at the reception, calling the Russian invasion tragic and senseless. Speaking of such conflicts threatening the globe, the pope said the world must find harmony.

Once again, the pope reaffirmed that Russia is responsible for the war in Ukraine. Francis was previously criticized for not doing so when the Russian invasion began.

The pope traditionally sends greetings to the capitals of the countries he flies over, however his outbound flight from Rome to Nur-Sultan avoided Russian airspace, sparing him a Telegram message to President Vladimir Putin.

The Congress of Leaders of World and Traditional Religions starts on Wednesday. Around 100 delegations from 50 countries are due to attend the two-day meeting.

On the first day of the congress, Wednesday, a joint prayer and bilateral meetings are on the agenda. Francis also plans to celebrate a Mass. On Thursday, a final statement by the religious leaders is to be read, then his return flight is scheduled.

A meeting with Russian Orthodox Patriarch Kirill of Moscow, which the Vatican had hoped for, will not take place. The Russian religious leader, who has always defended the war launched by President Vladimir Putin in Ukraine, recently bowed out from travelling to Nur-Sultan.

Kazakhstan, with a population of 19 million, is home to a small community of about 125,000 Catholics. Some 70% of Kazakhs are Muslim while 26% are Orthodox Christians. Pope Francis has praised the coexistence of the different religious groups there.

Facebook Inc., Twitter Inc. and Alphabet Inc. collectively removed hundreds of accounts tied to an alleged Iranian propaganda operation on Tuesday, while Facebook took down a second campaign it said was linked to Russia.

Facebook CEO Mark Zuckerberg said the accounts identified on his company’s platform were part of two separate campaigns, the first from Iran with some ties to state-owned media, the second linked to sources which Washington has previously named as Russian military intelligence services.

Officials in Iran, where it is a holiday to mark the Muslim Eid al-Adha festival, were not immediately available to comment. Moscow has repeatedly denied using hacking or fake social media accounts to influence foreign elections. The Russian embassy in Washington did not immediately respond to a request for comment.

The move by Facebook and others is the latest attempt by global social media giants to guard against political interference on their platforms. It comes as concerns are rising about foreign attempts to disrupt the U.S. midterm elections in November.

The United States earlier this year indicted 13 Russians for alleged attempts to meddle in U.S. politics, but the latest alleged Iranian activity, exposed by cybersecurity firm FireEye Inc. suggests the problem may be more widespread.

“It really shows it’s not just Russia that engages in this type of activity,” Lee Foster, an information operations analyst with FireEye, told Reuters.

FireEye said the Iranian campaign used a network of fake news websites and fraudulent social media personas spread across Facebook, Instagram, Twitter, Google Plus and YouTube, to push narratives in line with Tehran’s interests.

The Iranian mission to the United Nations did not respond to a request for comment.

The activity was aimed at users in the United States, Britain, Latin America and Middle East up through this month, FireEye said, and included “anti-Saudi, anti-Israeli, and pro-Palestinian themes” as well as advocacy of policies favorable to Iran such as the U.S.-Iran nuclear deal.

FireEye said the Iranian activity did not appear “dedicated” to influencing the upcoming election, though some of the posts aimed at U.S. users did adopt “left-leaning identities” and took stances against President Donald Trump.

That activity “could suggest a more active attempt to influence domestic U.S. political discourse” is forthcoming, Foster said, but “we just haven’t seen that yet.”

‘DISTINCT CAMPAIGNS’

Facebook said the Russia-linked accounts it removed were engaged in “inauthentic behavior” related to politics in Syria and Ukraine. It said that activity did not appear to be linked to the Iranian campaign.

“These were distinct campaigns and we have not identified any link or coordination between them. However, they used similar tactics by creating networks of accounts to mislead others about who they were and what they were doing,” the company said in a statement.

Facebook last month removed 32 pages and accounts tied to another misinformation campaign without describing its origins, but which U.S. lawmakers said likely had Russian involvement.

Microsoft said this week that hackers linked to the Russian government sought to steal email login credentials from U.S. politicians and think tanks, allegations the Russian foreign ministry described as a “witch-hunt.”

FireEye said the U.S.-focused Iranian activity ramped up last year, just months after Trump took office, with websites and social media accounts posting memes and articles, some of which were apparently copied from legitimate U.S. and Iranian news outlets.

In some cases, the domains for the fake websites like “US Journal” and “Liberty Free Press” were originally registered years before the 2016 election, in 2014 and 2013, but most remained inactive until last year, FireEye said.

Arabic-language, Middle East-focused websites appear to be part of the same campaign, the company added.

The technology companies variously said they linked the accounts to Iran based on user phone numbers, email addresses, website registration records and the timing of account activity matching Iranian business hours.

FireEye expressed “moderate confidence” about the Iranian origins, but said it has not been able to tie the accounts back to a specific organization or individuals.

Hundreds of thousands of people followed one or more of the Facebook pages implicated in the campaign, Facebook said.

It shared examples of removed posts, including a cartoon depicting an Israeli soldier executing a Palestinian and a fake movie poster showing President Trump embracing North Korean leader Kim Jong-un.

Postings cited by FireEye expressed praise for U.S. politicians and other Twitter users who criticized the Trump administration’s decision in May to abandon the Iranian nuclear pact, under which Iran had agreed to curb its nuclear weapons program in exchange for loosening of sanctions.

Some Twitter and Facebook accounts were designed to appear as if they were real people in the U.S., Britain and Canada, according to FireEye. The accounts used a combination of different hashtags to engage in U.S. culture, including “#lockhimup,” “#impeachtrump” and “notmypresident.”

Twitter, which called the effort “coordinated manipulation,” said it removed 284 accounts.

Facebook said it removed 254 pages and 392 accounts across its flagship platform as well as its Instagram service. Some of the accounts had events and groups associated with them.

The accounts spent about $12,000 to advertise through Facebook and Instagram using a variety of currencies, Facebook said. The company said it had notified the U.S. Treasury and State departments of the purchases, which may potentially violate sanctions.

Alphabet, which includes Google and YouTube, did not respond to a request to comment.
