Lebanon’s caretaker energy minister said on Friday that Qatar has expressed an interest in joining a consortium involving Eni and TotalEnergies that is exploring for oil in the eastern Mediterranean sea.

A post on the official cabinet Twitter account, citing Walid Fayyad, said the consortium was exploring for oil in blocks 4 and 9 in the region.

Earlier this week, Lebanon and Israel reached a historic agreement demarcating a disputed maritime border between them after years of U.S.-mediated negotiations, which opens the way for offshore energy exploration.
