TRIPOLI, Libya — Revolutionary fighters clashed with national army troops near Tripoli's airport, leaving one person dead, officials said Sunday.
The violence reflects the difficulties Libya's new leaders face as they try assert their authority over the disparate militias that overthrew Moammar Gadhafi.
Army spokesman Sgt. Abdel-Razik el-Shibahy said fighters from the western mountain town of Zintan, who control Tripoli's international airport, opened fire on two occasions on Saturday on the convoy of Gen. Khalifa Hifter, the commander of the fledgling national army.
He accused the Zintan revolutionaries of trying to assassinate Gen. Hifter, and said one guard was killed and four others wounded in the second attack.
Sgt. el-Shibahy also said the Zintan fighters mistakenly believed that the army was coming to attack them at the airport, which they have controlled since shortly after the capture of Tripoli in August.
"Zintan rebels opened fire on the convoy from left, right and front," he said. "They think that the army wants to take over the airport, but this is not the case."
Khaled el-Zintani, a spokesman for the Zintan fighters, denied they tried to kill Gen. Hifter, and blamed the violence on the army's failure to notify them that the general was coming.
The Zintan fighters, who control several checkpoints on the highway leading to the airport, said Gen. Hifter's convoy failed to stop at one of the security posts, prompting the Zintanis to open fire.
"What do you expect fighters to do when a heavily armed military convoy tries to pass checkpoints without previous notification?" Mr. el-Zintani said.
The clashes highlight one of the biggest challenges facing Libya's new leaders - establishing functioning security services, including an army and border guards.
Currently, semiautonomous militias that fought against Gadhafi still control key locations, including the capital's airport, and have proven reluctant to submit to the authority of the still weak interim national government.
Mr. el-Zintani said the revolutionaries are ready to hand the airport to a government agency "only if it is capable of protecting the airport from intrusions."
Mukhtar al-Akhdar, the Zintan commander at the airport, also rejected the army's authority.
"If this is a real army, why don't they go protect the borders instead of trying to take over the airport?" he said.
Gen. Hifter was named to replace military chief Abdel-Fattah Younis, who was killed in late July. Rebels insisted it was the work of Gadhafi's regime, but several witnesses said Younis was killed by fellow rebels.
