Saudi Arabia lets Qataris go on Haj, despite diplomatic row
Saudi Arabia will allow Qataris wanting to perform this year's Haj will be allowed into the kingdom, despite a diplomatic row between the two countries.
In a statement released on Thursday, the Saudi Haj ministry said Qataris and residents of the Gulf emirate could join the pilgrimage as they were already "electronically registered for the Haj" and they had the necessary permits from Riyadh and Doha.
But the ministry has imposed restrictions on Qatari pilgrims arriving by plane, saying they must use airlines in agreement with the Saudi authorities.They must also get visas on arrival in Jeddah or Medina, their sole points of entry into the kingdom.
This year the Haj is to take place at the beginning of September. Saudi Arabia and its allies Bahrain, Egypt and the United Arab Emirates cut diplomatic ties and imposed sanctions on Qatar in June, including the closure of their airspace to Qatari airlines.
The four Arab states accuse Qatar of supporting extremists and of growing too close to Shiite-dominated Iran, the regional arch-rival of Sunni-ruled Saudi Arabia.
