The United Nations Children’s Fund is among six charitable organisations that are set to use the funds to address a variety of urgent humanitarian needs in the world.

Direct Relief, International Medical Corps, King Salman Humanitarian Aid and Relief Center, World Food Programme and United Nations High Commissioner for Refugees are also due to benefit from the investment.

Returning for a fourth edition, GWB is scheduled to be held over six weeks and run by the Saudi Esports Federation.

It is set to begin tomorrow with a StarCraft ll tournament, a new addition to GWB, running until April 23 and featuring 24 players.

The all-women Counter-Strike: Global Offensive (CS:GO) event is due to be held for the first time from April 27 to 29, with six teams battling it out in a single elimination bracket for a $2.5 million (£2 million/€2.3 million) prize.

The same amount of money will be up for grabs when 16 teams set to compete in the Rocket League, due to be held from May to 4 and a Rainbow Six Siege tournament, scheduled to be staged from May 11 to 14.

GWB is set to conclude with the fifth and final tournament courtesy of the men’s CS:GO qualifiers from May 16 to 18.

Some of the best teams from around the globe are poised to compete for $2.5 million again and qualify to the finals at Gamers8: The Land of Heroes.

Gamers8 is set to take place in Saudi Arabian capital Riyadh from July 6 and offer a record prize pool of $45 million (£36 million/€40 million).

"Gamers Without Borders is back for its fourth annual event," said Prince Faisal bin Bandar bin Sultan Al Saud, chairman of the Saudi Esports Federation.

"Our core mission remains unchanged: to unite gamers worldwide behind humanitarian causes through their shared passion for gaming.

"Since its launch three years ago, Gamers Without Borders has raised over $30 million (£24 million/€27 million) in collaboration with our charity partners, making a massive impact on many lives across the globe.

"We are excited to continue leveraging this global platform to drive positive change in the world."

Crown Prince Mohammed bin Salman announced Saudi Arabia’s ambitious esports strategy last September with the aim of establishing the country as a global gaming hub by 2030 in a bid to boost the economy.

Saudi Arabia has been accused of sportswashing - using the staging of and involvement in sports events to improve the country's standing and mask concern over abuses of human rights - with its moves into esports, as well as traditional sports.

This month, Saudi Arabia's Public Investment Fund-run Savvy agreed to purchase United States-based Scopely for $4.9 billion (£3.9 billion/€4.5 billion), subject to regulatory approval.
Riyadh is set to host this year's Global Esports Games in December and has previously held two Global Esports Federation tournaments on the Global Esports Tour.
