There are no plans to scale back the Riyadh Metro projects despite the Saudi government clampdown on spending amid low oil revenues, said a report.

Besides the metro project, development works linked to the Haj and Umrah pilgrimages will also move ahead unhindered, reported the Arab News, citing a senior government official.

"The projects linked to the Riyadh Metro project are going as per schedule and operations of the 176-km project with six lines and 85 stations will begin by 2019," said the official quashing speculation the project could be scaled back or delayed following a slump in Saudi Arabia's oil revenues.

The government had recently clamped down on spending to curb an annual budget deficit of about $100 billion, slowing or suspending work on some projects.

The Ministry of Municipal and Rural Affairs is assessing the priority of the existing projects as per the recommendations of the Council of Economic and Development Affairs, said the report.

Under new directions, the ministry has put on hold the process of granting and signing all new projects, with the exception of projects concerning services for Haj and Umrah pilgrims, it added.
