Damascus:Seven bomb explosions have rocked the coastal cities of Tartous and Jableh in western Syria, leaving at least 121 people dead, a London-based monitor says. 

In Jableh, the attacks took the lives of at least 73 people and left scores of others injured on Monday morning, the Syrian Observatory for Human rights said.  

At least 48 people were killed in Tartous and many others injured in almost simultaneous bombings.

According to the report, one of the explosions occurred near a hospital when a bomber detonated his explosive vest.

Daesh claimed responsibility for the bombings. The Takfiri group, which is controlling parts of Syria and neighboring Iraq, has repeatedly targeted civilian structures like hospitals and schools.
