Russia and the US will meet with regional powers to discuss possible steps for Syria crisis settlement on October 15 in Lausanne, Switzerland, the Russian Foreign Ministry said in a statement.

Russia has vetoed a French resolution on Syria at the UN Security Council. The document was submitted by Paris a week ago and is countered by a Russian draft resolution still to be voted on.

At least eight people have been killed in suicide bomb attacks on a suburb of Damascus which is home to Syria's holiest Shia shrine, state media say.
