Led by Saudi Arabia, several states in the Middle East and Africa have severed ties with Qatar since June 5, accusing the gas-rich Gulf state of supporting terrorism and Iran. Qatar denies the allegations.
Saudi Arabia, the United Arab Emirates (UAE) and several other Sunni-majority countries have severed relations with Qatar since June 5, accusing the Gulf state of supporting terrorism based on its ties with the Muslim Brotherhood, Hamas and the Taliban.
Another point of departure is Qatar's ties with Iran, with whom it shares one of the world's biggest gas fields.
Qatar has denied the accusations and called the collective decision "unjustified." Kuwait, Turkey and the US have all urged a political solution as the bloc isolates Qatar using various ad hoc sanctions, including shutting down their airspace to Qataris and blocking import routes.
The dispute began in May when Qatar's Emir Sheikh Tamim bin Hamad al Thani was reported to have made statements on the state news agency supporting Iran. Doha said the statements were fabricated and disseminated via a hack.
Here are the latest developments in the crisis:

However, the four Arab countries at odds with Doha dismissed that deal as "insufficient."
