The Kremlin says a U.S. plan for safe zones in Syria should be thoroughly considered.

Asked to comment on a draft executive order that President Donald Trump is expected to sign this week, Russian President Vladimir Putin's spokesman, Dmitry Peskov, underlined the importance to "thoroughly calculate all possible consequences" of the measure. He noted Thursday that "it's important not to exacerbate the situation with refugees."

While suspending visas for Syrians and others, the order directs the Pentagon and the State Department to produce a plan for safe zones in Syria and the surrounding area within 90 days.

Safe zones, proposed by both Trump and Democrat Hillary Clinton during the campaign, were considered by the Obama administration years ago and ruled out, in part because of Russia's air campaign in Syria.
