Bahrain, Saudi Arabia, Egypt, and the United Arab Emirates on Monday decided to sever diplomatic ties with Qatar.

Bahrain was the first state to make a respective announcement, reported RIA Novosti news agency of Russia. According to the official statement published by the Bahrain News Agency, Manama’s move has been motivated by Doha’s persisting attempts to destabilize situation in Bahrain.

Bahrain gave Qatari diplomats 48 hours to leave the territory of the kingdom. Also, Manama suspended air and sea communication with Doha and banned Qatari citizens from visiting Bahrain, and prohibited its citizens from living and visiting Qatar.

Minutes later, Riyadh, Cairo, and Abu Dhabi made similar statements while Saudi Arabia and Egypt also suspended air and sea communication with Qatar.

The conflict between Qatar and its neighbors occurred one week after the Arab Islamic American Summit in Riyadh, when the Qatari news agency posted a speech on behalf of the country’s emir in support of building relations with Iran.

Later, the official representative of the Qatari Foreign Ministry said that the agency’s site was hacked, and the speech on behalf of the emir was published by hackers and has nothing to do with the Qatari leader.

Saudi Arabia, the United Arab Emirates, and Bahrain, however, considered this refutation to be unconvincing.
