The economic crisis and political paralysis in Libya have sparked a wave of protests in the country's main cities, from east to west.
The greatest tension was recorded in Tobruk, where the parliament building was stormed.
At the end of the day, the demonstrations against the deterioration of living conditions and the political stalemate degenerated in Cyrenaica.
Several television stations have reported that dozens of people have entered the building that houses the House of Representatives (empty, due to the holiday), carrying out looting.
The images showed thick columns of black smoke rising from the perimeter of the building after some young people had burned tires.
A bulldozer driven by a protester crashed into part of the complex's gate, making it easier to break into.
According to other media, part of the building was burned, police cars were also set on fire.
Other protesters, some of whom waved green flags of the
former regime of Muammar Gaddafi, they burned documents collected from the offices.
Parades also took place in Al Bayda, Misrata and Tripoli, in front of the headquarters of the national unity government, but without incidents.
The protest came as the Libyans have been struggling for days with continuous power cuts, aggravated by the blockade of several oil installations, caused by tensions between rival factions.
The anger of the citizens is directed against the political class, judged unable to give concrete answers to everyday problems, and which has not been able to call new elections, after the cancellation of those scheduled last December.
The square has called for a presidential and legislative vote later this year.
However,
the latest talks between the presidents of the two rival chambers - Tobruk parliament leader Aguila Saleh and Tripoli-based High Council of State chairman Khaled el-Meshri - failed to resolve key differences.
The prospect of elections appears further away than ever since the Tobruk House appointed a rival government to replace that of interim prime minister Abdulhamid Dbeibah, claiming his mandate had expired.
The past few weeks have seen repeated tensions between armed groups in Tripoli, which have sparked fears of a full-scale return to conflict.
The energy sector is also suffering from this paralysis.
In April, a blockade of two major oil export terminals and several fields began.
For the national body,
the Libyan National Oil Corporation, this block so far has involved losses of 3.5 billion dollars.
While the decline in gas production contributes to chronic blackouts, which last for a dozen hours a day.
