Vessels arriving directly from Israel or departing to Israeli ports would no longer be permitted to dock at Turkish ports. Turkish-flagged ships will also be prohibited from calling at Israeli ports
Turkish port authorities have begun informally requiring shipping agents to provide letters declaring that vessels are not linked to Israel and not carrying military or hazardous cargo bound for the country, according to two shipping sources.
The move is another step Turkey has taken against Israel after it last year severed trade with the country, worth $7 billion annually, over its war in Gaza with Palestinian militant group Hamas.
The sources said the harbour master's office had verbally instructed port agents to provide written assurances, adding that there was no official circular on the issue.
One of the sources said the instruction applied to ports across Turkey.
