Hi, I'm Carl Azuz.
Welcome to CNN STUDENT NEWS.
So as this new week begins, members of Congressare calling for better security at America's airports.
This comes after a shooting at one late last week.
LAX, Los Angeles International Airport, is one of the busiest in the U.S. Last Friday, it was shutdown after shots were fired inside the airport's terminal three.
Law enforcement officials say a gunman walked up to a security checkpoint and shot a TSAofficer, killing him.
Authorities say the gunman continuedthrough the terminal, wounding two other TSA officers and one passenger.
The alleged gunman was eventually shot by airport police and is now in the hospital.
The TSA officer who was killed was Gerardo Hernandez.
He was working as a travel document checker.
He is the first TSA officer to die in the line of duty since the agency was created in 2001.
The TSA is the Transportation Security Administration.
It was established after the 9/11 terrorist attacks in order to help make the nation's airportsand transportation systems more secure.
Our next story takes us to Iraq.
The last U.S. combat troops left that country nearly two years ago, but the fighting neverstopped.
More than 6,000 people have been killed this year, including hundreds of people in the month ofOctober.
A lot of the violence comes from the conflict between Iraq's Sunni and Shia populations.
Those are the two largest sects of Islam.
The civil war happening in Syria is also having an effect on what's going on in Iraq.
The violence never really ended in Iraq.
Much of the recent increase in attacks is blamed on the al Qaeda-led group, the Islamic State ofIraq.
The U.S. military used to boast of the success of having broken the terrorist organization'sback,
but now, nearly two years after the Americans fully withdrew, al Qaeda has undeniablyresurrected itself.
The country's security forces were never really capable of stabilizing the nation, especiallywithout U.S. support and technology.
And let's not forget that this is a nation where violence and politics go hand in hand.
The actions of the Shia-led government have made it easy for al Qaeda and other Sunniextremists to capitalize on the growing discontent, spread their influence, and increase theirattacks.
There have also been retaliatory attacks by the Shia against the Sunnis.
And in recent months, the death toll has reached levels not seen in years.
The U.N. envoy to Iraq called it an accelerated surge in violence, an acceleration the Syriancivil war has helped fuel, blurring battle lines as Al Qaeda expanded its Iraq operation into Syriaover the summer.
