The multilateral coordination to rid Syria of its chemical weapons and agents was essentially a Plan B for President Barack Obama after he failed to muster sufficient domestic or international support for a punitive strike on Syrian President Bashar Assad's government after a chemical attack in the Damascus suburbs in August.
The U.S. said more than 1,400 people were killed, including at least 400 children, though some organizations cited a significantly lower death toll. Assad's government blamed rebels for the attack.
The U.N. organized hoped to announce on Friday its strategy for removing the weapons by March 2014 and then destroying them. Officials have yet to confirm that they would destroy the weapons outside Syria, though they've called such an approach the "most viable option."
Syria is believed to possess around 1,000 metric tons of chemical weapons, including mustard gas and sarin. Its government met a Nov. 1 deadline to render inoperable all chemical weapon production facilities and machinery for mixing chemicals into poison gas and filling munitions.
Brende said details were being worked out about which Syrian ports would be used for loading the weapons onto the Norwegian cargo ship. He said the frigate would act as an escort to protect the material. He wouldn't say where the weapons would be taken for destruction.
With reports citing Albania as a possible destination, about 5,000 Albanians demonstrated Thursday outside the parliament and the prime minister's office. Albania has been cited as a possible venue because it destroyed its own stockpile. Whoever receives the weapons will likely get significant assistance from the United States, Russia and other powers.
Brende said he expected the U.S. will play a major role in the destruction effort.
Norway also announced a $14.5 million donation to the chemical weapons body and $16 million in additional humanitarian assistance for Syrian civilians. That takes total Norwegian humanitarian assistance during the war to $137 million.
Syria's conflict has killed more than 120,000 people in the past 2 years, according to activists, and displaced millions more.
