The first batch of chemical weapons materials left Syria on Tuesday - the first step of a UN-backed deal to rid of the country of its deadly chemical arsenal.
The UN and the international chemical weapons watchdog responsible for ensuring the weapons' destruction, said the materials were loaded on to a Danish vessel and left the northern port of Latakia.
A U.S. navy vessel will ultimately take the cargo out to international waters, where the materials will be destroyed.
The mission is part of a UN deal brokered by Russia and the U.S. that aims to eliminate Syria's chemical arsenal by the middle of this year.
The deal came in response to the chemical weapons attack last August that killed hundreds of civilians.
