On Saturday, Ukrainian President Volodymyr Zelensky announced that two additional ships had used a "temporary" shipping corridor in the Black Sea. The corridor was created after Russia withdrew from a UN grain export agreement in July.

“Two ships have successfully passed through our temporary ‘grain corridor’,” Zelensky posted on X, previously known as Twitter.

The president did not identify the vessels involved or say when they had completed their passage. Officials on Friday said two vessels had cleared the corridor — bringing to four the number that have used it.

Zelensky said Ukraine was “restoring true freedom of navigation in the Black Sea. Freedom requires determination.”

On Friday, a Ukrainian deputy prime minister said two vessels had passed through the corridor from the port of Pivdenny: one flagged in Liberia, the other in the Marshall Islands. The vessels were carrying pig iron and iron concentrate.
