Russia’s defense ministry on Thursday accused the United States of bombing the Syrian city of Aleppo.

"Just before 2 pm Moscow time (1100 GMT on Wednesday), two US Air Force A-10s flew into Syrian airspace from Turkish territory," defense ministry spokesman Igor Konashenkov said in a statement.

After reaching Aleppo by the most direct route, the US planes "conducted strikes against targets in the city," Konashenkov claimed.

Russia's defense ministry said Thursday that its air force had hit 1,888 "terrorist targets" in eight regions including Aleppo, Latakia, Hama and Homs provinces over the past week.

However, the defense ministry spokesman insisted that the air force's closest bombing target to Aleppo on Wednesday was more than 20 kilometers (12 miles) outside the city.

The ministry vehemently dismissed accusations that civilians had been targeted in the strikes, saying that "Russian aviation and Syrian government forces will never launch strikes on the civilian population."

Moreover, Russia said Thursday it was ready to discuss the possibility of a ceasefire in Syria as foreign ministers gathered in Munich in a bid to restart peace talks.

"We are ready to discuss the modalities of a ceasefire," deputy foreign minister Gennady Gatilov told journalists in Moscow, quoted by TASS state news agency. "That is what we will talk about in Munich."
