Riyadh: Saudi Arabia confirmed on Tuesday it plans to buy more F-15 fighter jets as part of a massive arms deal which the US State Department said in September could be worth up to $60 billion.

In the first comments by a Saudi official on the deal, assistant defence  minister Khalid Bin Sultan said the two sides remained in talks over final  details.

"Talks are continuing according to the agenda and part of it is the purchase
of the modified F-15 model," he told reporters on the sidelines of an airforce
graduation ceremony.

In September, US officials said Washington planned to sell weapons worth up
to $60 billion to Saudi Arabia including 84 new Boeing F-15 aircraft and 70
Apache helicopters.

But some defence industry officials and analysts have cautioned the deal could
be smaller. US defence firm Raytheon has put the total value at $25 billion.

The prospective arms sale is part of US efforts to shore up the military
capabilities of its Gulf Arab allies with which it shares concerns that Iran
might develop nuclear arms, a charge Iran denies.

The United States and Israel have not ruled out military action to stop Iran,
which says it only wants nuclear power to generate electricity.

Diplomats say an agreement with Saudi Arabia could kick off arms sales to the
other five countries in the Gulf Cooperation Council (GCC) - Bahrain, Kuwait,
Oman, Qatar and UAE - who are worried about retaliatory strikes in the event of war.
