(AP) BENGHAZI, Libya - Tribal leaders and militia commanders declared oil-rich eastern Libya a semiautonomous state on Tuesday, a unilateral move that the interim head of state called a "dangerous" conspiracy by Arab nations to tear the country apart six months after the fall of Muammar Qaddafi.
Thousands of representatives of major tribes, militia commanders and politicians made the declaration at a conference in the main eastern city of Benghazi, insisting it was not intended to divide the country. They said they want their region to remain part of a united Libya, but needed to do this to stop decades of discrimination against the east.
The conference declared that the eastern state, known as Barqa, would have its own parliament, police force, courts and capital Benghazi, the country's second largest city to run its own affairs. Foreign policy, the national army and oil resources would be left to the central government in the capital Tripoli in western Libya. Barqa would cover nearly half the country, from the center to the Egyptian border in the east and down to the borders with Chad and Sudan in the south.
Mustafa Abdul-Jalil, head of the Tripoli-based interim central government known as the Transitional National Council, warned the declaration "leads to danger" of eventually breaking up the North African nation of 6 million. But he also said it was to be expected because the east played a pivotal role in ending Qaddafi's rule.
"Some Arab nations, unfortunately, have supported and encouraged this to happen," he said, without naming any specific countries. "These nations are funding this kind of unacceptable strife," he added at a news conference in Tripoli. "What happened today is the beginning of a conspiracy against Libya and Libyans. "
Abdul-Jalil also appealed to Libyans for patience and resolve in the face of the country's mounting problems.
Fadl-Allah Haroun, a senior tribal figure and militia commander, said the declaration aims for administrative independence not separation.
"We are not talking about changing the flag or national anthem. We are talking about different administration, a parliament and managing the financial affairs," he said.
The east was the cradle of last year's uprising and civil war that ousted Qaddafi. In the early days of the revolt, the entire east came under opposition control and remained that way until Qaddafi fell in August. The eastern rebels set up the Transitional National Council, originally in Benghazi, which then moved to Tripoli and became the central government.
The goal for the east now is to revive the system in place from 1951 until 1963, when Libya, ruled by a monarchy, was divided into three states: Tripolitania in the west, Fezzan in the southwest and Cyrenaica in the east or Barqa, as it was called in Arabic.
Easterners say the step is necessary to end the marginalization their region suffered for decades under Qaddafi's rule. The former dictator focused development and largesse on the west, allowing infrastructure to decline in the east, an area that was a constant source of opposition to the regime.
Many in the east accuse the Transitional National Council of continuing to favor the west. After Libya declared liberation in October, the TNC and the interim government moved its offices to Tripoli in the west. The majority of Cabinet ministers are from the west.
The declaration underscored the weakness of the TNC, which has been largely unable to establish its authority around the country since the fall of Qaddafi in August and his subsequent death in October. The Council holds little sway even in Tripoli, where militias that arose during the anti-Qaddafi revolt have divided neighborhoods up into fiefdoms.
The prime minister of the interim government created by the TNC, Abdurrahim el-Keib, admitted that the government has not been up to the task.
"The government is not doing its job. My evaluation of its performance is not good," he said in an interview on state TV. "The steps we are taking are slow."
The TNC has called for national elections in June to select a 200-member assembly that will name a new prime minister to form a government and then write a constitution.
But the Benghazi conference illustrated one of the fundamental weaknesses in post-Qaddafi Libya the lack of political institutions. Over 42 years in power, Qaddafi stripped the country of any credible representative bodies. As a result, since his ouster, towns, cities, tribes and militias across Libya have largely taken authority into their own hands. The local power centers have confused and often thwarted the TNC's attempts to establish any national control.
Still Abdul-Jalil vowed Tripoli would remain the capital and said the nation would not go down the path that Qaddafi had warned of.
The Benghazi conference has no official status. The impact it has depends on how much influence its participants can wield among the population of the east and how strongly they push their demands on a resistant Tripoli. So far other regions have not made any moves to create their own states or call for a federal system.
At the conference, delegates raised the old Barqa state flag black with a crescent and a star. The gathering appointed Ahmed al-Zubair, Libya's longest serving political prisoner under Qaddafi, as leader of a planned governing council for Barqa state. Al-Zubair is a descendant of the former Libyan King Idris, whom Qaddafi ousted in 1969 coup. He is also a member of the Transitional National Council.
The conference said elections would be held in the east in two weeks to choose a governing council.
It rejected a draft law by the TNC on the planned June election that would give the east 60 seats in the assembly, compared to around 102 for the west. Drafters say that reflects the west's larger population, but easterners see it as a continuation of discrimination.
Among those who attended were top leaders of heavyweight eastern tribes, including the Ubaidat, Mughariba and Awajeer, which hold a powerful sway over large sectors of the population in the east. Also attending were commanders from the Barqa Army, a grouping of 61 eastern "revolutionary militias." Several senior Defense Ministry officials also attended and supported the declaration.
