Moscow called on Saturday for dialogue between Qatar and its neighbours in the Gulf, promising help in mediating the crisis, as Russia's foreign minister met his Qatari counterpart.

"We have observed with concern the news of this escalation," Russian Foreign Minister Sergey Lavrov said in opening remarks of his meeting with Qatari Foreign Minister Sheikh Mohammed bin Abdulrahman Al Thani in Moscow. 

"We cannot be happy in a situation when the relations between our partners are worsening. We are in favour of resolving any disagreements through ... dialogue."

Qatar is reaching out for support abroad as it has fallen out with its Arab neighbours, who accuse it of sponsoring "extremist" groups and accuse of sponsoring "extremist" groups and ties to Iran

Bahrain, Egypt, Saudi Arabia, the United Arab Emirates and a collection of other states have cut diplomatic ties with Qatar since Monday and are trying to blockade Qatar by air and sea.

Lavrov said that Russia is "ready to try to do everything in its power" to help resolve the crisis and said unity is needed to fight "terrorism".

"For us, unity is clearly necessary for maximum effect on this front," he said.
