Doha, 19 May 2019 (AlJazeera News)

A major gas pipeline from Qatar to the United Arab Emirates, Dolphin, experienced an outage for several days last month and Qatar filled the gap with additional liquefied gas supplies, a source familiar with the situation told Reuters news agency.

Qatar has been under a political boycott and economic blockade by its neighbours, Saudi Arabia,  the UAE, Bahrain and Egypt, who accuse Doha of supporting terrorism.

Qatar denies the claim.

In June 2017, then-chief executive of state-run Qatar Petroleum (QP) said Qatar would not cut gas supplies to the UAE despite the dispute between the two nations.

Saad Sherida al-Kaabi told Al Jazeera Arabic's Liqa al-Yaum (Today's Meeting show) that although there was a "force majeure" clause in the Dolphin pipeline agreement - which pumps around 2 billion cubic feet of gas per day to the UAE - Qatar would not stop supplies to its "brothers".

"The siege we have today is a force majeure and we could close the gas pipeline to the UAE," said Al-Kaabi, who is now Qatar's energy minister.

"But if we cut the gas, it does great harm to the UAE and the people of the UAE, who are considered like brothers ... we decided not to cut the gas now," Al-Kaabi added in the 2017 interview.

According to Al-Kaabi, a shutdown of the 364km Dolphin pipeline, which links Qatar's giant North Field with the UAE and Oman, would cause major disruptions to the UAE's energy needs.
