New volcanic fissure in Grindavik, Lava spills onto the streets.

The footage below shows a swathe of lava flow into the town, covering the side of one house as it goes up in flames. Later in the video, which was recorded from a helicopter, you can see where exactly the lava is coming from: a fissure that opened up close to the town a few hours ago. The bulk of the lava field is further away from the town, covering the landscape.
