The U.S. launched an operation to seize the Marinera oil tanker -- formerly known as the Bella-1 -- which has been linked to Venezuela and is currently in the North Atlantic, according to three sources familiar with the operation.

The operation is being carried out by the U.S. Coast Guard and other military assets. Russian military vessels were in the area as the situation unfolded. 

The U.S. Coast Guard has been tracking the tanker for the last two weeks after attempting to seize it on Dec. 20 when the empty ship was in the Caribbean and apparently headed to Venezuela.

On Dec. 31 the Russian Maritime Register of Shipping listed the ship -- with the new name of Marinera -- as a Russian vessel. The ship's crew also painted a Russian flag on the ship's side.

The Bella-1 previously flew a false Panamanian flag and was listed as part of Russia's so-called "shadow fleet," which Moscow is accused of using to evade international sanctions. The vessel was already under U.S. sanctions for carrying Hezbollah-owned cargo and for providing a form of support to the Iranian regime.

Director of National Intelligence Tulsi Gabbard on Tuesday praised U.S. service members and intelligence personnel following the seizure of Venezuelan President Nicolas Maduro.

In a post to X, Gabbard wrote, "President Trump promised the American people he would secure our borders, confront narcoterrorism, dangerous drug cartels and drug traffickers."

"Kudos to our servicemen and women and intelligence operators for their flawless execution of President Trump's order to deliver on his promise thru Operation Absolute Resolve," she added.

Gabbard, who ran for the Democratic presidential nomination in 2020, previously argued the United States should not intervene in Venezuela and has criticized what she has called U.S. led "regime-change" wars.

In January 2019, Gabbard wrote, "The United States needs to stay out of Venezuela. Let the Venezuelan people determine their future. We don't want other countries to choose our leaders -- so we have to stop trying to choose theirs."

In remarks last year, she described Trump's foreign policy as a break from what she called the "old Washington way of thinking," arguing that decades of U.S. foreign policy centered on regime change and nation-building had "held us back for too long."

She said the administration has replaced "toppling regimes" with a pragmatic and deal-focused approach, emphasizing security, prosperity and direct diplomacy.

The Russian and Iranian foreign ministries both issued new statements of support for Venezuela on Tuesday. Both nations have been long-term partners of Caracas and backers of deposed President Nicolas Maduro's government.

Russia's Foreign Ministry said the appointment of interim President Delcy Rodriguez demonstrates Caracas' "determination to ensure unity and preserve the vertical structure of power" in the face of what it called "blatant neocolonial threats and armed aggression from outside."

"We reaffirm Russia's unwavering solidarity with the Venezuelan people and government," the statement said. "We express our readiness to continue providing the necessary support to our friend Venezuela."

"We firmly believe that Venezuela must be guaranteed the right to determine its own destiny without any destructive external interference," the ministry added.

Iranian Foreign Ministry Spokesman Esmaeil Baghaei, meanwhile, said in a statement that "violating the sovereignty and territorial integrity of other countries is unjustifiable under any circumstances. The actions of the United States run counter to international laws and regulations."

"Such practices will have negative consequences for the entire international community," he added. "The actions of the United States should be condemned and opposed by the international community, and all parties involved must bear full responsibility for their actions."

Venezuelan Vice President Delcy Rodriguez addressed the nation on state television for the first time since President Nicolas Maduro's removal and demanded his release.

Rodriguez said Maduro was the only president of Venezuela and slammed the U.S. for its early morning strike.

"We had already warned that an aggression was underway under false excuses, under false pretexts, and that the masks had fallen and it had only one objective: regime change in Venezuela — and the capture of our energy, mineral, and natural resources," she said in Spanish.

Rodriguez also warned that "the people have mobilized"

"If something were to happen to him, the people must go to the streets, the armed forces must deploy across the country, and all institutions must activate — to defend what we are, as sons and daughters of Simon Bolivar," she said.

"We ride to defend the great homeland," she added.
