The government of Sunni-majority Qatar has long hosted and legitimized political leaders from the terrorist organizations known as the Muslim Brotherhood (MB), the Hamas Palestinian movement, and more recently the Afghan Taliban.

Saudi Arabia, the United Arab Emirates (UAE), Egypt, and Bahrain have severed ties with their fellow predominantly Sunni nation Qatar, accusing it of destabilizing the Muslim region with its support for Islamic terrorist organizations and plunging the Arab Gulf nations into a diplomatic crisis.

Qatari officials have repeatedly denied the allegations, dismissing them as “unjustified” and having “no basis in fact.”

“Qatar became a central target of the Saudi-Emirati-Israeli joint lobbying efforts for its perceived role in promoting the Muslim Brotherhood and hosting members of Hamas’ political bureau,” reports Al Jazeera.

In 2013, Qatar allowed the Afghan Taliban to open an official political office in its capital Doha. Although the Qatari government allegedly shut it down, Afghan Taliban leaders are believed to be still operating in Doha.

A senior Qatari official recently told Al Jazeera that Doha hosted the Taliban at the “request of the U.S. government,” led by former President Barack Obama at the time.

Under President Donald Trump, who has recently expressed strong support for Saudi Arabia, the United States joined the Sunni kingdom’s allies in condemning Qatar for supporting and assisting Iran and jihadist groups.

Hamas, officially deemed as a terrorist group by the United States, is considered one of Iran’s terror proxies.

Echoing comments made by Saudi Foreign Minister Adel al-Jubeir on Tuesday, House Foreign Affairs Committee Chairman Ed Royce (R-CA) blasted Qatar’s ties to terrorism on the same day.

Qatar “must stop supporting Hamas and the Muslim Brotherhood,” Jubeir told reporters.

During a hearing held by the House Foreign Affairs Subcommittee on the Middle East and North Africa hearing titled, “Challenges and Opportunities for the U.S.-Saudi Relationship,” Chairman Royce declared:

Qatar’s relationship with Hamas remains very concerning. Senior leaders of Hamas and the military wing of the Muslim Brotherhood – which is an Islamist group designated as terrorists by Egypt, Saudi Arabia, Bahrain, and the United Arab Emirates – all reside in Qatar today.

And earlier this month – and I think this is what is most concerning for all of us here – more Hamas tunnels were found under two U.N. Relief Works Agency schools in Gaza. Found underneath the schools in Gaza. So Hamas is still using civilians and children to hide its activities. And that, to me, does not sound like a legitimate resistance movement.

Qatar’s foreign minister recently referred to Hamas as “a legitimate resistance movement.”

The Sunni country “has doubled down on its relationship with Hamas,” noted Congressman Royce, later adding, “This practice needs to end now. There is no such thing as a ‘good terrorist group.’”

According to the House Foreign Affairs Committee, Hamas is responsible for for the death of more than 400 Israelis and at least 25 American citizens.

“Palestinian terrorism represents a grave threat to Israeli security and the prospects for a two-state solution,” said New York’s Eliot Engel, the top Democrat on the House panel, in a statement issued on May 26.“Congress must work to stop international support for Hamas and Palestinian Islamic Jihad, and foreign supporters of these organizations must understand the risks associated with perpetuating this perverse violence.”

The Obama administration refused to officially deem the Muslim Brotherhood as a terrorist group despite requests from Republican lawmakers.

President Trump is expected to support efforts to label MB a terrorist organization.

Unlike its predecessor, the Trump administration did not hesitate to refer to the Afghan Taliban as a “terrorist” group.

The U.S. has officially labeled the Afghan Taliban a terrorist organization.

Qatari foreign minister’s special envoy on counterterrorism told Al Jazeera that Doha allowed the Afghan Taliban to establish an office at the “request of the U.S. government” in 2013 and as part of the country’s “open-door policy, to facilitate talks, to mediate and to bring peace.”

Qatar “was facilitating the talks between the Americans, the Taliban and the government of Afghanistan,” claimed Mutlaq Al Qahtani, the FM’s envoy.
