Ask the LTTE to grant the civilians safe passage

I just came across this video: True, its taken by Sri Lankan government forces but what it shows can not be denied.

The video shows the LTTE blocking civilians from crossing over to cleared areas and designated no-fire safe zones by firing at them.

WHY? aren't the red-LTTE terrorist flag waving protesters demonstrating at Queens park right now not talking about this? Why are they not demanding that individuals close to the LTTE terrorist organizers in Canada address such concerns and work to free the trapped civilians?
