The Pentagon confirmed that the number of US soldiers who suffered a concussion after the Iranian missile strike on January 8 was 50, higher than initial estimates.

"To date, 50 US soldiers have been diagnosed with concussion trauma (TBI)," Lt. Col. Thomas Campbell, a Pentagon spokesman, said in a statement Monday.

Of these, 31 are treated in Iraq and have returned to work, Campbell confirmed. Eighteen American servicemen were taken to Germany for further evaluation and treatment. The number of US troops injured by this TBI is significantly higher than previously reported by the Pentagon on the consequences of Iran's Iranian ballistic missile strike on the morning of 8/1 on two bases. There are American soldiers stationed in Iraq.

The US Department of Defense initially said no people were injured in the attack, but later reported that 11 soldiers were diagnosed with TBI. That number was raised to 34 people last week and is now 50.

The Pentagon did not update information on eight soldiers who were sent back to the US last week for health checks and treatment. US officials admit TBI symptoms cannot be detected immediately.

Iran's Revolutionary Guards (IRGC) dawned on January 8 to launch 22 missiles at two bases of US and coalition forces in Iraq in retaliation for General Qassem Soleimani, commander of the Quds task force was killed. in the US air strike on January 3.

US President Donald Trump later said the missile strike "did not cause casualties" to US troops and caused only "minimal damage", while affirming Washington was ready to seek peace with Tehran.

The increasing number of soldiers injured by the TBI after the missile strike sparked political controversy following recent comments by Trump that soldiers only had "headaches" and "minor injuries".

William Schmits, chairman of the US Veterans of Foreign Wars (VFW), last week asked Trump to apologize for "false comments".

"We ask the President and the White House to join in the effort to help Americans understand the dangers the concussion poses to soldiers who defend the country in difficult times. More than ever, Our servicemen need comprehensive support in this challenging environment, "Schmits said.

The concussion was said to be a "typical form of injury" and an "invisible disease" for veterans who survived roadside bombings in Iraq and Afghanistan. The Pentagon and US Veterans Department estimate that about 408,000 soldiers worldwide have suffered some form of traumatic injury over the past 20 years.
