Jeddah: Saudi Arabia is spending 2.5 billion riyals (Dh2.4 billion) to expand the kingdom's airports, the state news-agency SPA reported on Sunday.

"These projects include the development, creation and expansion of 23 airports, locally, that will serve around nine million travellers annually," SPA stated.

The projects include the creation of a new 20 million riyal airport in Taif, located on the Western mountains, as well as a 300 million riyal expansion of the Najran airport in the south to be completed next year.

The country has vowed to spend more than $400 billion (Dh1.46 trillion) as part of its plans to diversify the economy and upgrade its infrastructure, creating more jobs for its population of 18 million Saudis.
