US President Barack Obama said we cannot turn a blind eye to the developments taking place in Syria in recent weeks.

In his weekly radio address on Saturday‚ he stressed the American lawmakers to back a military strike against Syria‚ as inaction is not an option for the United States.

President Obama called on Members of Congress‚ from both parties‚ to come together and stand up for a world we want to live in.

Obama told his war-weary country that America needs to use limited military force in Syria to deter future chemical weapons attacks, but said he did not want to enter into another costly and protracted war.

"This would not be another Iraq or Afghanistan," Obama said in his weekly radio and internet address, previewing arguments he will make in a nationally televised address on Tuesday.

"Any action we take would be limited, both in time and scope - designed to deter the Syrian government from gassing its own people again and degrade its ability to do so," Obama said.

A week ago, Obama said he felt limited strikes in Syria were needed, but added he wanted to ask Congress to authorise the use of military force.

Neither Democratic nor Republican lawmakers have been enthused about the prospect, partly because Americans strongly oppose getting involved in another Middle Eastern conflict.
