On Thursday, Zidan himself became victim of the insecurity plaguing the country since the 2011 civil war that toppled dictator Moammar Gadhafi. Militias kidnapped the prime minister and held him for several hours. Such armed groups, many including Islamic extremists, carry out daily violence nationwide and have defied attempts by the weak central authorities to control them. Many of them are connected to political groups that have representatives in the parliament.
On Friday, Zidan described his abduction as an attempted coup by his Islamist political rivals, using militias that he said are trying to "terrorize" the government and turn the country into another Afghanistan or Somalia.
Zidan, however, didn't name those specifically behind his kidnapping, only referring to the Libyan Revolutionaries Operation Room, the militia umbrella group loosely affiliated to Interior Ministry.
"I wish he named the political party he thinks is behind the operation," Sawan said, adding that Zidan told his lawmakers that he didn't mean Muslim Brotherhood. "We are against any action that violates legitimacy."
In addition to Zidan's abduction, militias have besieged key ministries in the capital and stormed ministers' offices this summer to force the parliament to pass a divisive law aimed at purging officials who served under Gadhafi from new government. The parliament passed the law virtually at gunpoint, highlighting the challenges facing Libya as it tries to transition to democracy.
The Muslim Brotherhood came second in the country's first parliamentary elections last year after a non-Islamist bloc led by the wartime prime minister. It has five ministers in Zidan's government.
A day before Zidan's abduction, parliament agreed to form a committee to discuss either an alternative to Zidan or to summon him for questioning.
"The government represented by the prime minister has had no success," Sawan said.
