Iraqi officials: At least 13 wounded in violence in Baghdad

Iraqi security forces fired tear gas and live rounds during clashes with anti-government protesters overnight and on Monday morning in Baghdad, wounding at least 13 demonstrators and prompting authorities to close key streets and thoroughfares leading to the city center, officials said.

The violence is the latest since protests in Iraq reignited last week after a brief lull amid soaring tensions between Washington and Tehran following a U.S. drone strike that killed top Iranian general Qassem Soleimani in Baghdad earlier this month.

The tear gas and live rounds were fired near the city's Sinak Bridge and nearby Tayaran Square, which have been the scene of violence in recent days, medical and security officials said.

As smoke rose over the city from the tear gas, tuk-tuks ferried the injured to hospitals.

A security official said at least nine arrests have been made so far after the National Security Council authorized security forces to arrest demonstrators seen blocking main thoroughfares and roundabouts.

The U.N. envoy to Iraq, meanwhile, urged Iraqi political elites to resume pushing for reforms and for protests to remain peaceful.

Any steps taken so far to address the people's concerns will remain hollow, if they are not completed," said Jeanine Hennis-Plasschaert in a statement issued by the U.N.

Violent suppression of peaceful protesters is intolerable and must be avoided at all costs. Nothing is more damaging than a climate of fear."
