An Iranian delegation has left Saudi Arabia without an agreement for its citizens to attend the haj pilgrimage this year, Saudi media have reported, a second failure by the Shiite power to strike a deal.

"At dawn on Friday, the Iranian mission expressed its desire to leave to home without signing the minutes of arrangements," the official Saudi Press Agency reported late on Friday.

Iran's top haj official Saeed Ohadi said there was still room to find agreement until Sunday night, according to Tehran's official IRNA news agency.

Saudi Arabia blamed Iran for the impasse.

"We witnessed a lack of seriousness by the Iranian side in dealing with the issue. It is yet another attempt by them to politicise the haj," Abdulmohsen Alyas, an under-secretary at Riyadh's Information Ministry, told Reuters.
