Washington - The US military has to had to cancel a planned shipment of munitions from a Greek port to a US warehouse in Israel due to objections from Athens, a Pentagon spokesperson said on Tuesday.

"I think the Greek government had some issue with the offloading of some of that shipment in their country and so we are finding alternative means of getting that entire shipment to its proper destination in Israel," Geoff Morrell told a news conference.

"I don't think we've come to a final resolution on how or when that will take place."
