This is the 10th such incident since late October, says Iraqi army BAGHDAD: Two rockets were fired at a military base near Baghdad airport housing US troops, the 10th such attack since late October, the Iraqi army said on Thursday. There were no casualties in the overnight attack, which follows one on the same base on Monday which wounded six members of Iraq’s elite US-trained counterterrorism force, two of them critically, the army said. Washington has expressed mounting concern about the flurry of attacks on US bases and diplomatic missions, several of which it has blamed on Shiite militia groups trained by its foe and rival for influence Tehran. Security sources have linked at least one attack last week to Kataib Hezbollah, a powerful Shiite faction close to Tehran and blacklisted by Washington. Iran holds vast sway in Iraq, especially among the more hard-line elements of the Hashd Al-Shaabi, a paramilitary force largely made up of Shiite militias. A US defense official told AFP the rocket attacks made the Hashd a bigger security threat to American troops in Iraq than Daesh, the militant movement which the US has vowed to help Baghdad wipe out. On Friday, the US imposed sanctions on three senior Hashd figures. Tensions between Iran and the US have soared since Washington pulled out of a landmark nuclear agreement with Tehran last year and reimposed crippling sanctions. Baghdad — which is close to both countries and whose many security forces have been trained by either the US or Iran — is worried about being caught in the middle. US officials say they are considering plans to deploy between 5,000 and 7,000 additional troops to the region to counter Iran. Anti-protester killed Meanwhile, demonstrators lynched a teenager accused of attacking a protest encampment in Baghdad on Thursday, police and witnesses said, in an attack that threatened to tarnish the protest movement’s broadly nonviolent image. Police said a dispute between a 17-year-old male and protesters culminated with the body of the youth being strung from a traffic light near Tahrir Square, the epicenter of the months-old anti-government protest movement. Earlier, police said protesters, some of whom have accused police of not protecting them from “saboteurs,” set fire to the nearby house of the young man. Video streamed live online showed security forces withdrawing before a crowd dragged a man along the ground while people kicked him. His body, dressed only in underpants, was then strung up by the feet from a traffic light. The corpse was later removed and taken to a forensic morgue, witnesses said. The morgue confirmed receiving a body. The brutal episode could radically change the situation for a protest movement that has claimed pacifism in the face of violence in which 460 people have been killed and 25,000 injured, mostly protesters. A statement signed by “the protesters of Tahrir” shared online denounced “a Machiavellian plan aimed at tarnishing the reputation of the peaceful protesters.” The thousands of protesters in Tahrir Square “had nothing to do with this morning’s events,” it concluded. As images emerged online, a Twitter account close to Muqtada Sadr addressed the Shiite cleric’s unarmed “blue helmets,” who deployed to protect protesters after unidentified gunmen attacked them last week. “If within 48 hours, the terrorists responsible are not identified, the blue helmets will have to withdraw from all the places where protesters assemble,” it wrote. Powerful pro-Iran militia leader Qais al-Khazali -- who was recently targeted by US sanctions -- denounced the “chaos” he has warned of since protests began. “How long will this chaos and lawlessness continue, these weak security forces and proliferation of weapons and dirty militias,” he asked on Twitter. Protesters accuse pro-Iran armed factions of playing a role in the killing and abduction of protesters.
