Survivors of the deadly wildfires in Greece described being forced into the sea as a "flamethrower" wall of flame came at them at the resort village of Mati.  Many didn't make it that far, with groups of the dead being found huddled together just 15 to 30 meters from the water.  "It burned our backs and we dived into the water," recalled survivor Kostas Laganos, "I said: 'My God, we must run to save ourselves'."  With at least 74 dead, an unknown number of people still missing, and hundreds injured by heat and smoke, this is worse than the wildfires of 2007 - the worst such disaster in Greece in recent years.  Prime Minister Alexis Tsipras has also declared three days of national mourning.

At least 77 are now dead in Japan's relentless heatwave, with 80 percent of the fatalities among those aged 65 and older.  Like other spots in the northern hemisphere in this new age of global warming, records are being shattered.  Kumagaya, a town outside Tokyo, set a new high at 41 C degrees; Tokyo itself charted a high of 40 C degrees, the first time that ever happened.  The government has declared the heatwave a "natural disaster".

Hundreds of people are missing after a dam collapse in Laos.  The Xenamnoy hydroelectric dam is 550 kilometers south of the capital Vientiane; it was reportedly designed to hold 1 billion tons of water, but the project hadn't yet been completed.  This started with damage reported in the dam late Sunday night local time, and by Tuesday several villages had been flooded.  Hydroelectric projects are the main component of the Laotian government's plan to become "the battery of Asia" and sell electricity to its neighbors.

Russia has arrested one of its top rocket scientists for allegedly leaking hypersonic missile secrets to NATO.  The state space agency Roskosmos confirmed that 74-year old Viktor Kudryavtsev is being held at a jail in Moscow.  He had previously won a state award for his research.  But in 2016, he and a group of scientists signed a letter in support of a fellow researcher and spacecraft designer who was convicted of treason.  Russia has been bragging recently about the development of hypersonic missiles which fly at five-times the speed of sound.

Syria is denying that one of its aircraft "blatantly" violated Israel's airspace before being shot down by the Israeli Defense Forces (IDF) near the Golan Heights.  An Israeli military spokesman said the Sukhoi warplane had crashed "most likely in the southern part of the Syrian Golan Heights", which is still udner Syrian control.  Syria usually doesn't test that border, but has been pushing jihadist and rebel forces further back as it winds up the civil war.

Singer Demi Lovato is reportedly in a stable condition in a Los Angeles hospital after was is described as a heroin overdose.  The 25-year old pop star has long struggled with addiction and mental health issues, and earlier this year released a song "Sober" in which she profusely apologizes for ending six years of sobriety.  Police reportedly found her in her Hollywood Hills home before Noon on Tuesday, local time, and administered Narcan to revive her before transport.

Canada's Banff National Park has welcomed something it hasn't seen in 140 years - three new Bison babies born in the park boundaries.  It's been less than 18 months since Bison were reintroduced to the Rocky Mountain natural wonderland and UNESCO World Heritage site in the western province of Alberta.  There used to be some 30 million bison in Canada until they were hunted almost to extinction in the 1800s.
