SANAA — Hundreds of protesters gathered outside the Yemeni president’s house in the capital Sanaa on Wednesday, June 11,  to call for the fall of the government, angry at a city-wide power cut about to enter its third day and severe petrol shortages.

President Abd-Rabbu Mansour Hadi has replaced five ministers in his cabinet amid angry street protests over power cuts and fuel shortages.

The blackout in the capital, widely blamed on the sabotage of oil pipelines by armed tribesmen with grievances against the government, is among the longest dark spells in almost three years of patchy electricity supply since Arab Spring protests unseated Yemen’s former president in 2011.

The pipeline attacks have deprived the state of revenue to buy fuel products, increasing the cost of food in the Arab world’s poorest country.

“Leave us, leave us, down with the corrupt leader!” angry residents chanted in front of the president’s house.

“This failure by the government has turned our lives into hell: no electricity, no gasoline or water. They have to leave us right away,” said protester Mohamed Sharaf.

Sanaa’s two million residents have been forced to light their homes with candles or private generators, fuel for which is increasingly expensive.

Hundreds of vehicles clogging gas stations have paralyzed traffic, causing the authorities to shut down streets including one that connects Hadi’s private home with the presidential palace.

A revolt by Shi’a militants in the north, secessionist unrest in the south and al-Qaeda militancy across the country has sapped Yemen’s economy, as oil and water resources decline.

Official news agency Saba reported that tribesmen had attacked power lines in the eastern province of Marib on Tuesday, leading to the blackouts in Sanaa and other areas.
