"Chemical experts and firefighters are working to secure at least 20 potentially dangerous chemical containers at the explosion-shattered port of Beirut, after finding one that was leaking, according to a member of a French cleanup team," the AP reports.Chemical containers were in many cases found punctured following the detonation of over 2,500 tons of ammonium nitrate. 

"French and Italian chemical experts working amid the remains of the port have so far identified more than 20 containers carrying dangerous chemicals," AP continues.

"We noted the presence of containers with the chemical danger symbol. And then noted that one of the containers was leaking," one French chemical expert working at the site said. "There are also other flammable liquids in other containers, there are also batteries, or other kind of products which could increase the risk of potential explosion," he added.
