A 95-year-old Second World War veteran from Ghana has set himself the challenge of walking two miles a day for a week to raise money for coronavirus charities.
Private Joseph Hammond hopes to raise $600,000 (£500,000) for frontline workers and vulnerable veterans across Africa.
Private Hammond fought with the British army in Burma, in the Gold Coast Regiment of the Royal West African Frontier Force.
Now, he says, he has joined the fight in a different type of war to help health workers defeat Covid-19 on the continent.
The money he raises will be used to purchase PPE for covid-19 frontline workers and vulnerable veterans in Commonwealth countries.
