On Wednesday, Russia gave the US very little notice before bombing rebel groups fighting the regime of Syrian President Bashar Assad, a close ally of Russia.
"This morning a Russian 3-star general walked across street to the US embassy in Baghdad and told them 'We bomb in 1 hour," the BBC's Paul Danahar tweeted.
"'Stay out of our way.'"
