US President Donald Trump has claimed credit for that pressure being placed on Qatar by Gulf neighbours who accuse it of supporting terrorism in the region.
He said his recent visit to Saudi Arabia was "already paying off" and the development might mark the "beginning of the end to the horror of terrorism".

Mr Trump's recent speech within the capital Riyadh, in which he blamed Iran for instability in the Middle East and urged Muslim countries to take charge in combating radicalisation, is seen as likely to have emboldened Gulf allies to act against Qatar.
"During my recent trip to the Middle East I stated that there can no longer be funding of Radical Ideology. Leaders pointed to Qatar - look!" Mr Trump tweeted on Tuesday.
He later tweeted: "So good to see the Al Jazeera visit with the King and 50 countries already paying off. They said they would take a hard line on funding... extremism, and all reference was pointing to Qatar. Perhaps this will be the beginning of the end to the horror of terrorism!"
