Toronto's Tamil diaspora protest against 'genocide'.

Genocide? Well if that's the case then its the LTTE committing genocide.

The Government of Sri Lanka has not prevented civilians form leaving the conflict areas in fact the Sri Lankan army is actively trying to extract the remaining civilian population, despite the Terrorist best efforts to disrupt that process by firing on civilians trying leave conflict zones and orchestrating a suicide bomb attack at a camp for displaced civilians.

So why would a Terror group claiming to represent Tamil rights in northern Sri Lanka deny parts of very population they claim to protect, gaining access to medicine, food and shelter? I don't know. Your guess is as good as mine, but logic states that the civilians are being used as a human shield by the LTTE.
