United States President Barack Obama talked with Australian Prime Minister Kevin Rudd about possible international interventions to Syria's recent chemical weapons attack against civilians. The White House said Mr Obama called Mr Rudd and both leaders were deeply concerned about the Syrian regime's alleged use of chemicals as weapons. In a statement, the White House also said they were talking about options to take to address the crisis.

The Obama administration strongly condemned the actions of the Syrian regime. It cannot be denied that the civilian attacks, which left hundreds of men, women and children dead, were due to chemical weapons. There Obama administration also believed the Syrian government was responsible.

White House spokesman Jay Carney told reporters that Mr Obama and his advisers are looking at options in response to Syria's violation of a prohibited act - the use of chemical weapons against a civilian population.

Australian Prime Minister Kevin Rudd said he doesn't believe the world will just "turn a blind eye" on Syria's chemical weapons attack. Almost 300 people died from the poisonous chemicals and thousands were injured and hospitalised.

Australia is a close ally of the United States. It is Australia's turn to sit as chair of the United Nations Security Council.

Mr Rudd said that if the international community and the UN will take no action, it would send a message of impunity to other regimes and their possible use of chemical weapons.

Australia will support retaliation against Syria even if the UN Security Council will fail to decide on an action. The country will have a vital role in the council to assist other members to reach an agreement.

Australia's Foreign Minister Bob Carr said the world will need to respond if UN inspectors come back with absolute proof that the Syrian regime used chemical weapons even if the council will not reach an agreement on the matter.

The United States and allied nations are currently preparing for a possible military response against Syria. If it happens, it would be the most aggressive option Western nations had to take to put an end to the almost three-year civil war in Syria.
