The sanctions imposed upon Qatar
by Saudi led alliance of Gulf States has worsened the situation in Middle East. The measures are more severe than during a previous eight-month rift in 2014, when Saudi Arabia, Bahrain and the UAE withdrew their ambassadors from Doha, again alleging Qatari support for militant groups. At that time, travel links were maintained and Qataris were not expelled.
A split between Doha and its closest allies can have repercussions around the Middle East, where Gulf states have used their financial and political power to influence events in Libya, Egypt, Syria, Iraq and Yemen.
The diplomatic broadside threatens the international prestige of Qatar, which hosts a large US military base and is set to host the 2022 World Cup. It has for years presented itself as a mediator and power broker for the region's many disputes.
Kristian Ulrichsen, a Gulf expert at the US-based Baker Institute, said if Qatar's land borders and air space were closed for any length of time "it would wreak havoc on the timeline and delivery" of the World Cup.
