Recep Tayyip Erdogan said he and Ukrainian President Volodymyr Zelenskiy had discussed sending grain to African countries.

"The situation in Djibouti, Somalia and Sudan is not good at all. If there is a problem in any other less developed countries, we will carry out shipments to these countries," Mr Erdogan said in an interview with Turkish broadcaster ATV.

The grain deal was brokered by the UN and Turkey in July, bringing to an end a five-month Russian blockade of Ukrainian ports that trapped millions of tonnes of grain and sunflower oil and sent food prices soaring.

The deal ends on 19 November and those involved still have to agree on extending it.

Russia had suspended support for grain exports but agreed this week to restart its participation in the agreement.
