*Six people were killed and at least 12 wounded in a late-morning shooting at a Safeway grocery store in Tucson, Ariz, this morning, reports the LA Times.

Among those injured is U.S. Rep. Gabrielle Giffords, who was reportedly shot point-blank in the head.

Giffords was taken to Northwest Medical Center, where she underwent surgery. A doctor at the hospital said at a news conference that she is in critical condition but that he is “optimistic” about her survival.

Here’s information about the shooter via HuffingtonPost.com:

Jared Laughner, the man who shot Congresswoman Gabrielle Giffords (D-Ariz.), was described by eyewitnesses as a young white man who looked like a “fringe character.”

Laughner shot Giffords and 12 others at a public event at a Safeway grocery store in Tucscon. He reportedly shot the congresswoman “point blank” in the head and may have come from inside the store. After shooting Giffords, he allegedly fired 20-30 rounds and hit “a number of people,” including a child. He attempted to flee after running out of ammunition and was tackled by one of Giffords’ staffers.

Eyewitnesses have described Laughner as “young, mid-to-late 20s, white, clean-shaven with short hair and wearing dark clothing.”

He was arrested upon arrival of the sheriff’s department.

Reverend Al Sharpton emailed this statement to EUR on the Gabrielle Giffords shooting:

“We are calling upon churches throughout America to pray for Congresswoman Gabrielle Giffords and the families of those that were wounded or killed in the tragedy that took place in Arizona.  In church services tomorrow clergymen ought to address the senseless violence that has too often raised its head of late in the social and political discourse of this country. We call on a thorough and expedited investigation of all aspects of this act.”
