HELSINKI, November 10. /TASS/. The duration of the Russian aerospace force’s operation in Syria will depend on the efficiency of the Syrian government army, Kremlin administration chief Sergey Ivanov said on Tuesday.

"As for the operation in Syria, I think it will be continued for certain time. As it was said at the beginning, its duration will depend on the Syrian army’s achievements on the ground," he told journalists. "So far the Syrian army is on an offensive. Let us wait and see the results."

"Any military operation is to end in political settlement," he added.

Enhanced cooperation between Russia, US in combating terrorism depends on parties’ will

It is possible to boost cooperation between Russia and the United States in the fight against terrorism, but everything depends on the political will of the interested parties, Kremlin Chief of Staff Sergey Ivanov told reporters.

Answering a question on whether more active cooperation between the United States and Russia in combating terrorism was possible amid the recent developments, Ivanov said, "[Yes, that’s] possible. Actually, contacts between Russia and the United States in countering terrorism never stopped, but now they are less intensive."

At the same time, he drew attention to the fact that "the prospects for their intensification and development depend not only on us, everything depends on the mutual political will and a concrete situation."
