LONDON (Reuters) - Iraq was quiet for a second day on Monday amid continuing Internet disruptions in many areas, while Washington called on Baghdad to "hold accountable those who violate human rights" after a protest movement that killed more than 100 people.

In Baghdad, the second largest Arab capital, the return to normal life is clear, and congestion has returned to the hubs of roads in this city of nine million people. Schools are again welcoming students after the protest movement disrupted the resumption of schooling.

Departments and businesses have opened their doors, but access to social networks is still not possible.

The official toll of violence in Baghdad and southern Iraq has also reached more than 100 dead and more than 6,000 wounded.

The identity of those who carried out the violence remains unclear, as the authorities spoke of "unknown snipers."

Despite the cessation of violence in Baghdad and the south, social media networks remained blocked after activists were able to portray the violence widely.

So far, the Iraqi authorities have not commented on the three-quarters of the country, according to the non-governmental organization specialized in information security «NetBlocks». Only the Iraqi Kurdistan region in the north of the country has not been affected.

"This almost complete cut-off of the network imposed by the state in most areas seriously limits media coverage and prevents transparency about what is happening," Netbooks said.

Network providers assured their customers that they could not give information.

For its part, announced US diplomacy, the night before last, that Secretary of State Mike Pompeo, called on the Iraqi government to show "maximum restraint." "Those who have violated human rights must be held accountable," he said.

Washington said Pompeo made the remarks in a "recent" telephone conversation with Iraqi Prime Minister Adel Abdul Mahdi, who said on Monday he had spoken to the US secretary of state.
