Shafaq News/ The media center of the Syrian Democratic Forces announced that it had taken a series of security measures following the rocket attack that targeted a U.S. military base in Deir Ezzor countryside.

"Yesterday evening at 07:45 North and East Syria time, military bases belonging to our forces to fight ISIS in the Haql al-Omar area, in Deir Ezzor countryside, were subjected to dangerous rocket attacks", SDF said in a statement.

No causalities were recorded. 

SDF indicated that it carried out several precautionary operations in the surrounding areas to prevent any attacks carried out by ISIS terrorist cells.

A military base housing U.S. forces in the Haql al-Omar area, in the Deir Ezzor countryside (eastern Syria) was targeted by a rocket, from sites controlled by pro-Iranian factions west of the Euphrates River, according to the Syrian Observatory for Human Rights.

The bombing comes hours after "Hezbollah Brigades" vowed to respond to the death of 4 of its fighters in U.S. raids on the Iraqi-Syrian borders. 

However, the official military Spokesman for the Global Coalition, Wayne Marotto, confirmed in a tweet, "At approx. 7:44 PM local time, U.S. Forces in Syria were attacked by multiple rockets. There are no injuries, and damage is being assessed."
