A month after drifting in the southern waters of the Atlantic Ocean, two identified Iranian warships docked into Rio de Janeiro on Sunday as Brazilian President Luiz Inacio Lula da Silva gave the green light despite receiving pressure from the United States not to.

According to USNI News, the two vessels—forward base ship IRIS Makran and frigate IRIS Dena—were deployed to make a port visit in late January. However, this was pushed back when the newly-elected Brazilian President bowed to US pressure and declined Iran’s request to dock in Rio.

It is noteworthy here, though, that the Lula was scheduled to meet his US counterpart, Joe Biden, in Washington when he denied the Iranian ships off the Brazilian port.

Perhaps this was a gesture to avoid awkwardness for the duration of his journey. Because as soon as he came back, he gave the green light to dock the warships via Vice Admiral Carlos Eduardo Horta Arentz, the deputy chief of Brazil’s Naval Staff.

From February 26 to March 4, the Iranian surface group is permitted to moor in Rio.
