COLUMBUS, Ohio (AP) -  The Latest on a car-and-knife attack on the Ohio State University campus (all times local):

7:35 p.m.

A leader of a Somali community association says a man who launched a car-and-knife attack at Ohio State University drove his siblings to school as normal beforehand.

Hassan Omar says Abdul Artan's mother said she didn't know anything was wrong until police showed up at her door.

Omar said Tuesday the mother told him nothing seemed different about her son, who she said was enjoying his education.

Artan was a Muslim who prayed daily and stewed over the treatment of fellow Muslims.

Omar says he was shocked by Monday's attack because of the amount of effort the community puts into preventing people from being radicalized.

Democratic U.S. Rep. Adam Schiff is a House Intelligence Committee member and says he's seen no evidence Artan communicated with overseas terror organizations.

Artan was killed by police.

4:10 p.m.

An official at Catholic Charities of Dallas says the organization briefly offered aid to Ohio State University attacker Abdul Razak Ali Artan and his family when they first moved to the U.S. in 2014.

CEO Dave Woodyard told KXAS that Artan arrived in Dallas with his mother and six siblings on June 5, 2014. Woodyard says the Somali family arrived at Dallas-Fort Worth International Airport from Pakistan through Kennedy Airport.

He says the organization gave the family shelter and aid as part of the government resettlement program. He says the group's records show the family received shelter for 23 days before leaving for Ohio.

Artan was killed Monday by a university police officer after driving his car into pedestrians on campus and attacking people with a knife.

4 p.m.

An Ohio State medical official says three of the 11 people injured in an attack at Ohio State University remain hospitalized and are expected to make complete recoveries.

Dr. Andrew Thomas provided an update during a Tuesday afternoon news conference.

Engineering professor William Clark also spoke to reporters after being discharged Tuesday. Clark says he was struck by attacker Abdul Razak Ali Artan's car, tossed in the air and landed on concrete. Clark says he had surgery for deep cuts in his right leg.

Clark says he and some of his students were outside a classroom building after a fire alarm sounded for a gas leak. Clark says he will withhold judgment about Artan until more facts are known about his motivations.

Artan was killed by a university police officer.

This story has been corrected to show the doctor's name is Andrew Thomas, not Andrew Scott.

3:05 p.m.

A union official says the officer who killed a man to stop an attack at Ohio State University responded according to his training and is grateful for the outpouring of support he's received from fellow police and the public.

Local police union president Jason Pappas says university officer Alan Horujko (huh-RUJ'-koh) is on paid administrative leave. Pappas says standard procedure requires that the 28-year-old officer see a psychologist and get a new firearm before he gets back to work.

Officials say Horujko was nearby when a Somalia-born student plowed a car into a group of pedestrians Monday morning and began stabbing people with a butcher knife. Police say the officer shot the driver in less than a minute.

Authorities say they're investigating whether it was a terrorist attack.

12:30 p.m.

The director of a mosque attended by the Ohio State attacker says numerous programs are in place to help youth and prevent self-radicalization.

Horsed Noah says he wasn't familiar with Abdul Razak Ali Artan, the OSU student born in Somalia who police say carried out the car-and-knife rampage that left 11 people hurt Monday morning.

Noah says thousands can attend services on busy days at the mosque on Columbus' west side.

The mosque just celebrated its second anniversary and serves mostly Muslims from Somalia and other East African countries, many of whom live nearby.

Noah mentors youth at the mosque, which also offers "Meet a Muslim" programs and helps Somali parents learn to communicate with their children, especially as they assimilate faster to life in America.

Noon

A law enforcement official says Ohio State University attacker Abdul Razak Ali Artan moved to the U.S. with his family from Pakistan as refugees in 2014.

The official briefed on the investigation wasn't authorized to publicly disclose details of the case and spoke to The Associated Press on condition of anonymity. The official says Artan is originally from Somalia but lived in Pakistan from 2007 until 2014.

It's not uncommon for refugees to flee their home country to live elsewhere before permanently resettling in another country.

Authorities say Artan plowed a car into pedestrians on campus and then began stabbing people with a knife Monday morning. Eleven people were injured.

A police officer fatally shot Artan within a minute of the attack. Artan was an OSU student.

The Columbus City Council president calls the attack at Ohio State University "an isolated incident" and says blame should be on the attacker, not the diverse Muslim and Somali communities from which he came.

Authorities identified the attacker as Abdul Razak Ali Artan, an OSU student born in Somalia. They say he plowed a car into pedestrians and then began stabbing people in an attack that left 11 people hurt.

A police officer killed Artan. Police say they're investigating whether it was a terrorist attack.

City Council President Zach Klein and other councilmembers planned to visit the Ibnu Taymiyah Masjid and Islamic Center in northeast Columbus on Tuesday to talk with Muslim and Somali community members. The councilmembers planned to attend a noon prayer service there.

11:20 a.m.

An Ohio State University student says he escaped serious injury by fending off the man who staged a car-and-knife attack at campus.

Andy Payne tells the Springfield News-Sun (http://bit.ly/2gS7XZb ) he'd gone outside Monday morning because of a fire alarm and watched as fellow OSU student Abdul Razak Ali Artan jumped the curb in his car and struck pedestrians outside a classroom building.

The 27-year-old Payne says Artan attacked him with a knife as he approached the car to help the injured.

Payne says he stopped Artan from stabbing him and escaped by grabbing the knife with his left hand. Payne is recovering at his suburban Columbus home after undergoing surgery Monday to repair tendons and nerves in his left hand.

Artan was fatally shot by a police officer.

10:55 a.m.

A law enforcement official tells The Associated Press the attacker at Ohio State University railed on his Facebook account against U.S. interference in countries with Muslim communities.

Abdul Razak Ali Artan warned about Muslims he described as belonging in "a sleeper cell, waiting for a signal." The posting said that if the U.S. wanted "Muslims to stop carrying lone wolf attacks, then make peace with 'dawla in al sham,'" or the terror group known as the Islamic State.

The official wasn't authorized to discuss the ongoing criminal investigation and spoke on condition of anonymity.

Artan specifically protested the killing of Muslims in Burma, where the head of the U.N. refugee agency in Bangladesh last week said a Muslim minority group was suffering violence tantamount to ethnic cleansing at the state's hands.
