• As Police says 9 dead, including suspect, at suburban Dallas home

The US has significantly diluted a package of new proposed sanctions against North Korea, dropping an oil embargo and enforceable naval blockade in the hope of avoiding a Chinese veto at the UN security council.

A revised draft seen by the Guardian and circulated by the US mission to the UN on Monday will impose a ban on imports of North Korean textiles and put a cap on Pyongyang’s imports of crude oil and refined petroleum products.

But other elements were dropped from a much stronger version proposed by the US last week, including the first asset freeze directed at Kim Jong-un, a complete ban on oil sales to his regime, and a mandate for warships from any member state to inspect ships suspected of carrying contraband to or from North Korea, and to enforce inspect using “all necessary measures”.

The Pyongyang regime threatened retribution against Washington for any new sanctions measure threatening to inflict “the greatest pain and suffering” the US has ever encountered.

A diplomatic source at the security council said that the revisions in the draft had been made with the aim of securing acquiescence from China and Russia, who expressed serious reservations about the original version. The US called for the security council in the wake of North Korea’s sixth, and most powerful, nuclear test on 3 September.

“This is a text designed for adoption,” the source said. “If they were running it to force a veto, they wouldn’t have made the revisions.”

In the meantime, nine people, including a suspect who was fatally shot by an officer, have died after a man opened fire during a gathering to watch football at a suburban Dallas home, police says.

Plano police Chief Gregory W Rushin said at a last afternoon news conference that one of two people hospitalised after the Sunday night shooting had died.

An officer responding to a report of shots fired at about 8 PM confronted the suspected shooter and opened fire, killing the suspect. Police then found the nine gunshot victims seven were dead and two were taken to the hospital.

“The first responding officer actually heard gunshots taking place inside the residence,” police spokesman David Tilley said.

Rushin said the officer approached the house from the back and saw bodies in the backyard before confronting the suspect inside.

Police have not yet confirmed the identities of those killed or the suspect. Rushin did say that the suspect “was known by people in the residence,” adding the suspect had a “relationship with that house.”

Debbie Lane told WFAA television station that her daughter, Meredith Lane, was among those killed in the shooting. She said her daughter owned the home and had recently divorced her husband of six years. She said her daughter, a native of Georgia, was hosting a party to watch football games, starting with the Atlanta Falcons vs. The Chicago Bears and continuing with the Dallas Cowboys vs. The New York Giants.

“She was a cook, and a quite fine one, and she loved hosting friends and families,” Debbie Lane said.

All of those killed and injured were believed to be adults.
