I'm Paul Moss, and in the early hours of Sunday, the 14th of December, these are our main stories.

A gunman allied to Islamic State has killed three Americans at an army base in Syria.

The Israeli government has announced the killing of a senior Hamas commander.

And Chile goes to the polls on Sunday.

But will voters choose the far right or a communist?

Also in this podcast, Belarus celebrates the release of political prisoners, but opposition leaders insist their struggle continues.

And a manhunt is underway in the US state of Rhode Island after a mass shooting at one of the country's top universities.

Intelligence sources estimate there are still between 5,000 and 7,000 members of the extremist Islamic State group at large in Iraq and Syria, some of them in sleeper cells which carry out regular attacks.

And there was a terrible reminder of that on Saturday, when three Americans were killed by a gunman at an army base close to Syria's famous ruins of Palmyra.

Donald Trump, speaking next to a rather noisy helicopter, reacted to the news.

It was an ambush, terrible.

We also have three wounded.

They seem to be doing pretty well.

But we mourn the loss.

The president, the new president of Syria is, as they told me, and I'm not surprised, he's devastated by what happened.

This was an ISIS attack on us and Syria.

It's pointed that Mr Trump took the trouble there to refer to the stance of Syria's president, Ahmad al-Sharah, a sign of how things have changed in the relations between Washington and Syria.
