Images show a freight ship, the 'Valsamitis', in the southern Ukrainian port of Chornomorsk, being loaded with grain. The vessel, participating in the Grain from Ukraine program and supported by the UN World Food Program, will go to the Kenyan port of Mombasa. The UN warned on Wednesday that agreements to enable grain shipments from war-torn Ukraine, one of the world's biggest cereal producers, were in "difficult territory." The hard-won Black Sea Grain Initiative was brokered by the UN and Turkey last July and renewed in November. It is up for renewal again on March 18. IMAGES
