Russia Targets in Syria Chosen in Cooperation With Assad Army

U.S. worried that Russia might be overreaching in strikes against ISIS.

LONDON— -- Russia has launched at least 20 air strikes in northern Syria, its Defense Ministry said today, marking Russia’s biggest Middle East intervention in decades.

"It does appear that they were in areas where there probably were not ISIL forces, and that is precisely one of the problems with this whole approach,” U.S. Defense Secretary Ash Carter said Wednesday, using the government’s acronym for ISIS.

Kremlin spokesman Dmitry Peskov told reporters today that “these targets have been determined in coordination with the Syrian armed forces," and that "all the flights took place after air surveillance and careful verification of the data provided by the Syrian military."

Jets flying at higher altitudes than the Syrian air force emitted no noise to alert the people below to raids, Reuters reported, killing at least 33 civilians, including children. But Peskov stressed that Russian jets did not target any civilian infrastructure.

"We agreed on the imperative of as soon as possible, perhaps even as soon as tomorrow, but as soon as possible, having a military-to-military deconfliction discussion," Kerry said.

Such an approach would ensure that Russian aircraft do not interfere or clash with Western warplanes, which are already operating in the area.
