Yes, the news is true and the messages you are receiving via Whatsapp are. I live in Salmyia and the smell is just everywhere and unbearable, just a funny smell like something is rotten! there are no more news on the incident, how or why! but someone should come out to the public and speak since people are saying its a leak of a dangerous gas called H2S
Below is a video of the leakage that happened today in the morning, and rumors are saying it actually happened twice and the second was at night at like 8:30PM
Update: They had to set the oil well on fire to completely get rid of the smell.
