A deal allowing the safe Black Sea export of Ukrainian grain was renewed on Saturday for at least 60 days - half the intended period - after Russia warned any further extension beyond mid-May would depend on the removal of some Western sanctions.

The pact was brokered with Russia and Ukraine by the United Nations and Turkey in July and renewed for a further 120 days in November. The aim was to combat a global food crisis that was fueled in part by Russia's Feb. 24, 2022, invasion of Ukraine and Black Sea blockade.

The deal had been set to expire on Saturday.

The United Nations and Turkey said on Saturday that the deal had been extended, but did not specify for how long. Ukraine said it had been extended for 120 days. But Russia's cooperation is needed and Moscow only agreed to renew the pact for 60 days.
