Two adults and four children have been shot dead in Texas.

A 15-year-old girl was also seriously injured in the incident at a house in a suburb of Houston.

A male suspect in the shooting was surrounded by police in a nearby cul-de-sac and surrendered a short time ago after a standoff with officers that lasted around 3 hours.

"It appears this stems from a domestic issue with a breakup in the family from what our witness has told us," Assistant Chief Deputy Constable Mark Herman said.

The victims were killed at a house in Spring, Houston, before armed officers chased and cornered a silver car containing the suspect.

The car was eventually barged by a large police truck, which appeared to pin it to the ground, while marksmen gathered nearby.

A second armoured vehicle arrived shortly afterwards to corner the suspect, who stayed in the vehicle for around three hours.

Despite being surrounded by marksmen, and having his car virtually crushed by the armoured truck, the suspect remained "cool as a cucumber", police said.

After lengthy negotiations he emerged from the vehicle with his hands raised, sinking to his knees before being arrested and detained.
