Just 13 hours after the El Paso Massacre, another young white male in America grabbed an assault weapon and killed nine people in an entertainment district in Dayton, Ohio.  Police were patrolling the area at about the time most of the bars and taverns close - about 1:00 AM Sunday, local time - when they heard the shots fired by 24-year old Connor Betts, a suburban man armed with a .223 caliber rifle - probably an AR-15 assault weapon.  Officials say it was all over within 60 seconds, and the officers shot and killed the gunman.  Among the dead was the gunman's own sister 22-year old Megan Betts.  It's not clear if she was a target.  Police say they haven't determined a motive.

State officials in Texas saying they will pursue the death penalty against 21-year old Patrick Crusius, the avowed white nationalist and fan of Donald Trump who murdered 20 people at a Walmart store in El Paso, Texas on Saturday in the US.  Crusius drove ten hours across the state from his home town of Allen to the racially diverse El Paso, where left a poorly written manifesto on a website popular with young racists in which he castigated immigration and race mixing.  Federal prosecutors say this is considered a domestic terrorism case, which will allow the FBI to get involved and determine if Crusius had co-conspirators in other states.

Australia is considering a US request to join a coalition protecting shipping traffic in the Persian Gulf.  "We are deeply concerned by the heightened tensions in the region, and we are strongly condemning the attacks on shipping in the Gulf," said Defense Minister Linda Reynolds as quoted by the ABC.  "The request the US has made is a serious and complex one, that's why we're giving this request serious consideration.  We will ultimately as we always do, decide what's in our sovereign interests."  Iran's state media says Revolutionary Guard forces have detained a second tanker, accusing the operators of "smuggling fuel for some Arab countries".  Last month, Iran seized British-flagged tanker the Stena Impero in the Strait of Hormuz, saying it had collided with a fishing vessel.  That was seen as retaliation for the UK seizing an Iranian tanker near Gibraltar.

The search for a pair of Canadian teens suspected of killing a NSW man has turned to the Nelson River in rugged northern Manitoba.  A Royal Canadian Mounted Police dive team arrived after a damaged rowboat turned up on a particularly swampy part of the river near Gillam, the last town where 18-year old Bryer Schmegelsky and 19-year old Kam McLeod were last seen.  They charged with murdering Vancouver university professor Leonard Dyck, and suspected of murdering Australian Lucas Fowler and his American girlfriend Chynna Deese, who were shot to death and discovered by the Alaska Highway in northern British Columbia on 15 July.

The chief ideologist and "Brother Number Two" of Cambodia's Khmer Rouge has died at the age of 93.  Nuon Chea was appealing last year's conviction on genocide charges from from the Maoist group's brutal rule in the 1970s in which as many as 2.2 million people were killed, which became the subject of the movie "The Killing Fields".  Only two members of the Khmer Rouge's former leadership are serving prison terms for the atrocities.
