The militant Islamic State group has released a video warning the US that fighters await in Iraq if Barack Obama sends troops there.
The video was released after the US military stepped up its campaign against Islamic State (IS) militants with a series of airstrikes across Iraq and Syria.
The 52-second film shows militants blowing up tanks, wounded US soldiers and others about to be killed.
It then shows a clip of the US president saying that combat troops will not return to Iraq, ending with a text overlay that reads "fighting has just begun".
Chimps have a killer instinct
Chimpanzees and humans have one key trait in common - both are natural born killers.
Evidence suggests our closest animal relatives have an almost psychopathic tendency towards violence and slaughter.
A widely held theory is that chimps only turn on each other when humans disrupt their forest habitats or food supplies.
The new research indicates this is wishful thinking. In reality, chimps fight and kill to get what they want and "eliminate rivals", say the authors.
Clifford prison term appeal

Skunk's beer ordeal stinks
A skunk with a beer can stuck on its head had to be rescued near a US fraternity house in Ohio.
Police said a resident called them about the skunk's predicament and they found the animal banging around trying to get the can off and running into shrubs.
Skunks are known for the offensive spray they can emit when threatened. But Sgt. Jon Varley says an animal control officer was able to free the skunk without getting sprayed and then released it.
