DAMASCUS, April 9 (Xinhua) -- The Russian-Iranian joint operation room in Syria said on Sunday that Syria's allies will strongly respond to any aggression against Syria, adding that the U.S. attack is a dangerous precedent and a violent aggression on the sovereignty of the Syrian state and people.
"What America has done in attacking Syria is crossing red lines and from now on we will strongly respond to any aggression by any party and America knows well our capability to respond," said the statement.
It added that the allies of the Syrian government will increase their support to the Syrian army following the U.S. missile strike on a Syrian air base.
Earlier on Friday, the United States targeted the Shayrat air base in Homs Province with nearly 60 Tomahawk missiles, killing six Syrian soldiers and nine civilians, including four children, and destroying nine warplanes, according to the Syrian government.
The U.S. government said the attack on the air base came in retaliation for the strikes by the Syrian air force on the town of Khan Sheikhoun on Tuesday.
Activists accused the Syrian army of firing toxic gas on the town, killing 70 people, while the Syrian army said the strike targeted an arm depot containing toxic gas, blaming the rebels for stockpiling such materials.
"The arrogant America hasn't waited any permission and didn't respect the countries in the UN and attacked Syria so blatantly without waiting the results of the investigation in the Khan Sheikhoun case," Sunday's statement said.
According to the statement, the allies of the Syrian government are closely following the movement of the U.S. in northern Syria and northwestern Iraq.
"They should know that we are aware of their attempts to control that geographic spot, and that makes them illegal occupation forces," it said.
"Russia and Iran will not allow America to control the world and will stand in its face with all available power no matter what will happen," the statement concluded.
