Monday’s attack, which was carried out by drone, threw those options into doubt. An executive whose ocean transportation company operates a ship waiting to load grain at Reni said he was waiting to hear whether Monday’s attack would affect insurance premiums, which were already high. Given Russia’s withdrawal from the deal that guaranteed safe passage for commercial vessels through the Black Sea, insurance premiums are likely to be prohibitively expensive for shipowners, analysts said. But some shipowners may decide to travel to Ukrainian ports even with the elevated risk, if they receive assurances from the Turkish and Ukrainian governments, said Yoruk Isik, an analyst with the consultancy Bosphorus Observer, in Istanbul. In recent days, Russia has launched a series of aerial assaults on Odesa, a Black Sea port in Ukraine.
