Iran’s paramilitary Revolutionary Guard seized a Panamanian-flagged oil tanker in the strategic Strait of Hormuz on Wednesday, the second such capture by Tehran in under a week amid heightened tensions over its nuclear program.

According to the AP, The taking of the oil tanker Niovi renewed concerns about Iran threatening maritime traffic in the strait, the narrow mouth of the Persian Gulf through which a fifth of all crude passes. It also comes amid the disappearance of a crude oil tanker in southeast Asia believed to be carrying Iranian crude oil amid reports it may have been seized by the United States.

The U.S. Navy published surveillance footage shot by an aerial drone of about dozen Guard vessels swarming the tanker on Wednesday morning. The drone had been on a routine patrol in the area and saw the seizure, though the Navy did not receive a distress call from the Niovi itself, 5th Fleet spokesman Cmdr. Timothy Hawkins said.

Those Guard ships “forced the oil tanker to reverse course and head toward Iranian territorial waters off the coast of Bandar Abbas, Iran,” the Navy said.

“Iran’s actions are contrary to international law and disruptive to regional security and stability,” the 5th Fleet said in a statement. “Iran’s continued harassment of vessels and interference with navigational rights in regional waters are unwarranted, irresponsible and a present threat to maritime security and the global economy.”

Iran acknowledged the seizure, with the judiciary’s Mizan news agency quoting the Tehran prosecutor’s office as saying that a judge ordered it impounded over an unspecified complaint.

Shipping registries show the Niovi as managed by Smart Tankers of Piraeus, Greece. A woman who answered the phone at the firm declined to immediately comment on the seizure. The Niovi had been coming from dry-dock repairs in Dubai, bound for Fujairah on the eastern coast of the United Arab Emirates without carrying any cargo, according to the data firm Refinitiv.
