Late on Tuesday night, the Jordanian government announced it was reducing its level of diplomatic representation in Qatar and cancelling the local registration for Al-Jazeera TV.
Meanwhile, Qatar's Foreign Minister Sheikh Mohammed bin Abdulrahman Al Thani Qatar will never surrender to the pressure being applied by its Arab neighbours and won't change its independent foreign policy to resolve disputes that have put the region on edge.

Jubeir declined to confirm a list of 10 demands published by Al Jazeera, which included shutting down the Doha-based news channel, but added that Qatar knew what it needed to do to restore normal relations.

The Gulf countries have ordered their citizens out of Qatar and given Qataris overseas 14 days to return home. The efforts by these countries on Qatar's behalf has raised questions about the future possibility of Doha aligning more closely with them and edging away from the GCC and US.

The United Arab Emirates has warned that anyone expressing sympathy for Qatar could face up to 15 years in prison, as a regional crisis escalates. Russia denied Wednesday that it hacked the agency after a CNN report quoted anonymous USA officials saying they suspected Russian hackers.
The ministry did not say who it suspected carried out the attack, though it thanked the FBI and the British National Commission for Combating Crime for assisting it in its investigation.
On May 24, Qatar said its state news agency was hacked over two weeks ago and fake news items embedded, a claim that US Intelligence investigators confirmed earlier this week.
