The Norwegian Nobel Committee announced the winner earlier on Friday (October 9) for the United Nations food agency's efforts to combat hunger and improve conditions for peace in areas affected by conflict.
Phiri added that the achievement would provide additional motivation for WFP's aid workers.
The Rome-based organization says it helps some 97 million people in more than 80 countries each year, and that one in nine people worldwide still do not have enough to eat.
WFP runs a logistics service that has dispatched medical cargos to over 120 countries throughout the pandemic to help governments and health partners fighting COVID-19.
It also has provided passenger services to ferry humanitarian and health workers where commercial flights were unavailable.
