It's one of the most chilling testimonials of a genocide in our backyard.

Confirmed reports state that Myanmar soldiers are going house to house executing civilians in the northern Buthidaung township.

We are also seeing horrific, gory photographs of butchered Rohingyas, in social media, coming out of Arakan state.

This is, however, just the beginning.

Asean must act immediately if we do not want the ongoing conflict to descend into a civil war.

Prime Minister Najib Abdul Razak was the first Asean leader to stand up for the Rohingya and vehemently condemn Myanmar for its targeted persecution against the minority community, despite the bloc's non-interference policy.

This is commendable but Najib must once again lead the call to lobby Myanmar to stop the killings immediately.

The prime minister must convene an urgent meeting with his counterparts to strongly reprimand Myanmar, failing which the rogue state must be expelled from the regional grouping, for Myanmar is Asean's biggest shame.

We need to send a strong message to Myanmar as its military has been upping the violence against the Rohingya since June 2012.

The current targeted killings are worse than the attacks against the Rohingya in October last year.

And while it's imminent that the military tackles any form of insurgency, it must also abide by international human rights laws and protect civilians.

But according to reports, the violence has left more than a hundred people dead, hundreds more displaced, villages and properties burnt.

And while I write this, we continue to see photographs and video clips of butchered Rohingyas and burning villages.

As such, a political solution is imminent and crucial. And all Asean member states must have the political will to stand united against the killings and displacement of civilians by the Myanmar military.

If we fail to act now, Asean will surely have another Cambodia to deal with.
