Iran's oil minister on Tuesday dismissed an output freeze deal between the world's top two producers Saudi Arabia and Russia as "a joke", the ISNA news agency reported.

"Some neighbouring countries have increased their production over the years to 10 million barrels per day and export this amount, then say let's all freeze our oil production," Bijan Zanganeh said.

"They freeze production at 10 million bpd and we freeze at 1 million bpd. This is a very funny joke."
