A foreign-flagged ship arrived in Ukraine on Saturday for the first time since the start of the Russia-Ukraine conflict in February, and will be loaded with grain, Ukrainian Infrastructure Minister Oleksandr Kubrakov said.

Writing on Facebook, he said the Barbados-flagged general cargo ship Fulmar S was in the Ukrainian port of Chernomor.

Meanwhile, the first shipment of Ukrainian grain since February will no longer arrive in the northern Lebanese port city of Tripoli on Sunday as planned, Ukraine's embassy in Beirut said. 

"Tomorrow's arrival of (the) Razoni ship is postponed," the embassy told AFP in a message on Saturday. Updates regarding an arrival ceremony "will be sent later when we get information about (the) exact day and time of the arrival of the ship," it added.
