Aden: Thousands demonstrated in south Yemen’s main city Aden on Saturday to demand a return to independence a day after President Abd Rabbo Mansour Hadi said only autonomy was on the table.

The rally in Aden’s central Parade Square came as southerners marked the anniversary of the end of British colonial rule in 1967, which created an independent state that lasted until union with the north in 1990.

Demonstrators waved southern flags and banners proclaiming: “Yes to Freedom and Independence,” and: “Our Goal is the Reclamation of Statehood.”

Security forces set up checkpoints across the city and on its outskirts to control the large number of demonstrators travelling in from adjacent provinces, but kept their distance from the rally itself.

Fuad Rashed of the hard line, pro-independence wing of the Southern Movement, which organised the rally, told AFP: “Through this demonstration, which is open to all groups without exception, we want to advance towards independence.”

The movement also has a more moderate wing, which is ready to accept autonomy within a federal Yemen, but on condition that it be one of just two component units, north and south.

The moderates quit a national dialogue earlier this month in protest at proposals for multiple units for the north to reflect the divisions between its mainly Zaidi Shiite northern highlands and mainly Sunni southern highlands and coast.

The southerners fear that such an arrangement would dilute their power in a federal system.

In a speech late on Friday to mark the independence anniversary, Hadi, who is himself a southerner, said there could be no question of renewed statehood for the south.

“Yemen’s unity will continue to be a sacred value,” he said, adding that those who advocated secession lived in a world of “illusion”.

Union in 1990 was followed by a secession attempt by southern leaders in 1994 that sparked a brief but bloody civil war.

The conflict ended with an occupation of the south by northern forces that laid the ground for many of the disputes over land and jobs that still fan southern resentment.

Southern grievances are one of the main issues facing the national dialogue, alongside those of Zaidi rebels in the northern highlands.

The talks, which were supposed to have ended in September, are a key part of the UN-backed transition process that saw veteran strongman Ali Abdullah Saleh step down in early 2012 after 33 years in power in Sana’a following 11 months of deadly Arab Spring-inspired protests.

The transition government is also facing a persistent insurgency by Al Qaida, which took advantage of the unrest to seize large swathes of the south and east and remains active despite an offensive by the army last year and intensified US drone strikes.
