A police officer shot and wounded a man today outside baggage claim at a Dallas airport after the man attacked a woman believed to be the mother of his children and then threatened the officer with a large rock, The Associated Press quoted the police as saying.

'There doesn't appear to be any other weapon present than the rock,' Dallas Police Assistant Chief Randall Blakenbaker said.

Video posted by Instagram user @flashyfilms and credited to Bryan Armstrong shows people scattering on the sidewalk outside the baggage claim door at Dallas Love Field.

An officer in a yellow vest is seen pointing his gun, and at least nine gunshots can be heard. A man repeatedly yells 'stand down!' and a woman is heard screaming.

Asked why the officer fired so many rounds at a man holding a rock, Blankenbaker said only that he did not know how many shots were fired.

Some airport operations were temporarily disrupted, but the airport remained open. Spokesman Jose Torres said that some people after hearing shots ran through security so everyone had to be re-screened.

Officials warned that delays could last several hours.

The man, who was not identified, was taken to a hospital. Torres said he was not critically wounded. Traveler Lucinda Fonseca told WFAA-TV that she and her husband were coming out of the baggage claim area when they saw police approaching the man throwing rocks and one of the officers drew a gun.
