American President, Donald Trump is showing his human side.

At the just concluded G20 summit in Hamburg, Germany, he pledged $639 million, about 195 billion Naira so that people in conflict and drought-stricken Nigeria, Somalia, South Sudan and Yemen do not starve to death.

Of the funding, $121 million, about 37 billion Naira will come to Nigeria.

Trump's pledge came during a working session of the G20 summit of world leaders in Hamburg, providing a "godsend" to the United Nations' World Food Programme, the group's executive director, David Beasley, told Reuters on the sidelines of the meeting.

"We're facing the worst humanitarian crisis since World War Two," said Beasley, a Republican and former South Carolina governor who was nominated by Trump to head the U.N. agency fighting hunger worldwide.

The new funding brings to over $1.8 billion aid promised by the United States for fiscal year 2017 for the crises in the four countries, where the United Nations has estimated more than 30 million people need urgent food assistance.

"With this new assistance, the United States is providing additional emergency food and nutrition assistance, life-saving medical care, improved sanitation, emergency shelter and protection for those who have been affected by conflict," USAID said in a statement.
