State owned oil giant Saudi Aramco is hiking up security at offshore sites, according to media reports.
The firm has received a number of bids from defence firms, Reuters has reported.
Sources told the news agency that supposed bidders include Raytheon Co of the United States, Germany’s Rheinmetall AG, Leonardo’s Selex ES Saudi Arabia and General Dynamics.
Aramco declined to comment on the contracts or its security plans, but said in an emailed statement that it “considers the security of its employees and facilities a top priority and are of the utmost importance.”
