SANA, Yemen — Tens of thousands of Yemenis marched in protest on Saturday against Shi’ite rebels who hold the capital, amid a power vacuum in a country that is home to what Washington describes as Al Qaeda’s most dangerous offshoot.
Some 20,000 people hit the streets of the capital, Sana, where demonstrators converged on the house of President Abed Rabbo Mansour Hadi, who resigned Thursday along with his Cabinet. It was the largest protest since the rebels, known as Houthis, swept into the capital in September.
Protesters carried banners and chanted slogans denouncing the rebels and demanding the restoration of the president. Scuffles involving knives and batons broke out in one instance in Sana when the rebels tried to block one procession, leaving two demonstrators and one Houthi injured.
‘‘Houthi aggressors, out of the capital,’’ went one chant, and ‘‘Hadi, Hadi, return. Your people are awake,’’ said another. One slogan accused the Houthis, who adhere to a sect of Shi’ism, of being clients of mostly Shi’ite Iran, while another said they were colluding with Hadi’s predecessor, longtime autocrat Ali Abdullah Saleh.
Security officials said Houthi gunmen fired on demonstrators in the port city of Hodeida, injuring three people.
Security officials, who spoke on condition of anonymity because they were not authorized to brief reporters, said that tens of thousands also demonstrated in the cities of Taiz, Ibb, and Dhamar with similar demands.
In Dhamar, protesters formed a human chain, demanding the ‘‘restoration of the state.’’ Many across the country described the Houthi power grab as a ‘‘coup.’’ The Houthis, who say they are fighting corruption, said in a statement Friday night that they would work to bring about a smooth, democratic transfer of power after the resignations.
The Houthis, who captured several cities as they drove south from their northern strongholds last summer, seek greater representation in government ministries and on a committee to rewrite the country’s constitution. They now face mounting pressures and internal divisions however, and there have been signs they do not want to rule the country outright and would prefer that Hadi remain as a figurehead president.
Ali al-Bukhaiti, a member of the group’s political arm, resigned Friday over what he described as a dangerous political polarization that could turn regional and secular and eventually break up the country.
