President Donald Trump earlier signaled support for protests in the Islamic Republic and threatened new strikes

The US has opened a new air and missile defense coordination cell at a key airbase in Qatar amid rising tensions with Iran and President Donald Trump's promises to assist protesters in the Islamic Republic.

In a statement on Tuesday, US Central Command said the facility at the Al Udeid Air Base, which houses some 10,000 troops, will be comprised of American and allied personnel and seeks to "enhance integrated air and missile defense." The new cell is also intended to tighten information-sharing, threat warning, drills and joint responses for air and missile defense, US officials said.

Reuters reported, citing three unnamed diplomats, that some personnel had been advised to leave the base by Wednesday evening for unknown reasons. The agency noted that the US took the same measures ahead of strikes on Iranian nuclear facilities last summer, while the Al Udeid Air Base came under a retaliatory attack from Tehran at the time.

The move comes amid soaring US-Iran tensions, with Trump offering symbolic support for the riots, which began in late December as protests over the sharp devaluation of the Iranian rial and the sanctioned country's cost-of-living crisis. The US president, in particular, has urged Iranians to keep protesting and said "HELP IS ON ITS WAY," while also warning of "very strong" action in case of a harsh crackdown on rioters. At the same time, Trump did not rule out talks with Iran.

Iran's foreign minister, Abbas Araghchi, said Tehran did not seek war but was prepared for it, and Iranian officials have warned neighboring states that host US forces that they could face retaliation if Washington attacks. Officials in Tehran have also insisted that the US and Israel had had a "big hand" in fostering the current protests.

Meanwhile, Saudi Arabia, Oman, and Qatar have privately pressed Washington not to strike Iran, warning that a conflict could trigger severe regional instability and disrupt oil markets, the Wall Street Journal reported.
