Report: U.S. Takes Quiet Steps to Weaken Syrian Regime

The U.S. government has been quietly trying to block arms and oil shipments from Iran to Syria in a bid to accelerate the fall of Syrian President Bashar Assad, The Wall Street Journal reported late Sunday.

Citing unnamed U.S. officials, the newspaper said the efforts are aimed at getting Iraq to close its airspace to flights between Iran and Syria that U.S. intelligence believes are carrying arms for Syrian pro-government forces.

The United States also declared Sunday that it would "hold accountable" any Syrian official involved in the release or use of the country's chemical weapons.

Fears have been rising in the West after reports that Assad might be prepared to use his arsenal of chemical weapons to save his embattled regime.

According to The Journal, Washington has also tried to keep ships believed to carry arms and fuel for Syria from passing through the Suez Canal.

One ship, the Amin, currently seeking permission to enter the canal is owned by a subsidiary of Islamic Republic of Iran Shipping Lines, the report said.

U.S. officials are holding talks with the Egyptian government in an effort to block the Amin's passage, arguing that it isn't properly flagged and doesn't have internationally recognized insurance, the paper noted.

It added that the United States also has been providing intelligence about Syria to the Turkish and Jordanian militaries working closely with the rebels.

This information includes imagery from military satellites and other surveillance equipment that provides details about Syrian military sites that could be helpful to the rebels, The Journal pointed out.

U.S. officials acknowledge that despite their efforts, some shipments of arms and fuel for Syria have slipped through.
