New Doha oil deal draft says all OPEC members must join: sources

DOHA (Reuters) - A new draft of a deal to freeze oil output that is to be agreed later on Sunday in Doha has a line saying all OPEC members should be part of the agreement, industry sources said. The change appears to be a major obstacle for clinching a binding deal, given that OPEC member Iran had decided not to send representatives to the meeting.
