Shipping activity near the Strait of Hormuz has increased, NBC reported.
At least 16 ships passed through the Strait of Hormuz on April 11, one of the busiest days since the war began, the report said.
According to the network, three tankers carrying crude oil passed through the strait. They flew the flags of China, Hong Kong and Liberia.
Earlier, US President Donald Trump announced that the military had begun clearing Iranian naval mines from the Strait of Hormuz. According to the US Central Command, two destroyers, the USS Frank E. Peterson and the USS Michael Murphy, were involved in the mine clearance operation.
After the US-Israeli operation began, Iran announced a halt to trade through the Strait of Hormuz, through which 15-20% of the world's oil, condensate and petroleum products pass, as well as over 30% of liquefied natural gas supplies. Amid reports of mines in the strait in March, Trump called on European and Asian countries to send their ships to the Strait of Hormuz to jointly secure the sea route.
Trump later criticized NATO countries for their refusal to cooperate in the operation.
