A group of Arab nations early on Monday extended a deadline for Qatar to respond to their list of demands in a diplomatic crisis roiling the Gulf by 48 hours, saying Kuwait's emir requested the delay as part of his efforts to mediate the dispute.

Saudi Arabia, the United Arab Emirates, Egypt and Bahrain cut off ties with 2022 FIFA World Cup host Qatar on June 5, restricting access to their airspace and ports and sealing Qatar's only land border, which it shares with Saudi Arabia.

They issued a 13-point list of demands to end the standoff June 22 and gave the natural gas-rich country 10 days to comply.

The joint statement early Monday by the four Arab nations said they expected Qatar to respond to their demands later in the day. The new deadline would expire late Tuesday or early Wednesday. Foreign ministers of the four Arab nations will meet Wednesday in Cairo to discuss their next moves, Egypt said Monday.
