On April 6, 2021, a new group, Zulfiqar Forces, which is part of the Iranian-backed 'Islamic Resistance in Iraq,' released on its Telegram channel a poster threatening to launch an attack inside the United States.
The poster depicted a masked fighter wearing the group's uniform and holding a machine gun, against the backdrop of the U.S. Capitol Building, edited to appear in ruins. The Arabic text at the bottom of the poster read "Companion of Death," highlighting the fearlessness of the group's fighters.
On September 15, 2020, the group released a statement claiming responsibility for the August 27, 2020 rocket attack on the U.S. Embassy in Baghdad, saying that the attack was motivated by the group's vow to avenge the killing of IRGC Quds Force Commander Qassim Soleimani and PMU Deputy Commander Abu Mahdi Al-Muhandis.
The next day, the group posted footage on Telegram documenting the rocket attack on the U.S. Embassy.
Several Telegram channels appear to be affiliated with the group, including channels which serve as a content pipeline for supporter of Iran-backed militias in Iraq.
It is worth noting that over the past few months, many Telegram channels affiliated with these militias have posted graphic content threatening to target U.S. forces not only in Iraq, but also inside the U.S., including Washington DC.
For example, on March 2, 2021, Kawtheryoon Electronic Team posted on Telegram a message in English claiming that the so-called Islamic Resistance Factions in Iraq are stronger than they were in the past, and are expanding, so much so that they have the capacity to carry out operations within U.S. territory, including Washington DC. 
"The axis of resistance today is stronger than before. Resistance cells are rooted even in America and its capital," said the post, which also warned that U.S. forces should withdraw not only from Iraq, but the Middle East entirely.
