Officials of Gulf Arab states traditionally wary of Iran were silent on Friday about an initial deal intended to curb the nuclear program of their regional rival, and state-owned media made only passing mention of the development.

The main evening television news in Saudi Arabia broadacast a segment on the agreement only 40 minutes into its program.

A senior Gulf Arab official said any reaction would come in coming days not from individual countries but from the Gulf Cooperation Council (GCC), an alliance of Saudi Arabia, Kuwait, the United Arab Emirates (UAE), Qatar, Oman and Bahrain.
