On the eve of his perilous escape from his home country last month, Sudanese photojournalist Mohamed Zakaria left his camera equipment with a friend, not sure if he would ever see it again.

Sudan's humanitarian catastrophe has been the largest in the world for many months. More than half of Sudan's 45 million people need urgent relief aid.More than 12 million are displaced, including nearly two million refugees in neighbouring countries - Chad, Egypt, and South Sudan.

Some food security specialists fear that as many as 2.5 million people could die from hunger by the end of this year.While the roots of Sudan's hunger lie in decades of economic mismanagement, the legacy of devastating wars, and drought made worse by climate crisis the trigger for today's famine is the use of starvation as a weapon.War erupted in April last year between the SAF, under Gen Abdel Fattah al-Burhan, and the paramilitary Rapid Support Forces (RSF) led by Gen Mohamed Hamdan Dagolo, known as "Hemedti".

The war soon devastated Sudanese communities.Like a swarm of human locusts, RSF militiamen rampaged through the capital, Khartoum, stripping it bare of anything that could be pillaged and resold. The force also vandalised vital infrastructure such as hospitals and schools.

The same story was repeated wherever the RSF advanced.

The breadbasket regions of Gezira and Sennar along the Blue Nile, a place of vast irrigated farms, have been ravaged.The flow of migrants from Mexico in the US has long overshadowed relations between the two neighbours and became a defining issue in the 2024 White House election race that culminated in Trump’s resounding victory this month.

Under US diplomatic pressure, Mexico has been conducting its largest ever migrant crackdown, bussing and flying non-Mexican migrants to the country’s south, far from the US border.But Trump campaigned on a promise to seal the US-Mexico border and his threat to impose 25% tariffs was seen as an attempt to force Mexico into doing more to stop the migrants from reaching the US southern border.

The Mexican government has in turn demanded that the US take action to stop the flow of weapons being smuggled from the US into Mexico.Sheinbaum told reporters on Thursday that she would raise the issue of guns with Trump "in due time".
