Russia seized the initiative over Syria Wednesday after a diplomatic flurry that saw it host President Bashar al-Assad on his first foreign visit since 2011 and schedule talks involving the war's key players. Assad met Vladimir Putin and thanked his Russian counterpart for launching air strikes against his opponents in Syria, with both leaders also agreeing during talks late Tuesday that political steps must follow military operations.

Moscow announced afterwards that Foreign Minister Sergei Lavrov would meet Friday with US Secretary of State John Kerry and their Turkish and Saudi counterparts to discuss Syria.

The talks between Putin and Assad focused mainly on military developments, with the Russian president pledging ongoing support but also urging a political solution to end the war, the Kremlin said, according to AFP.
