The US says all sides have agreed steps to bring the violence in Syria "to an end tonight", after Israeli strikes hit the capital Damascus.
Syria has "welcomed the efforts" to resolve the situation, but Israel has yet to comment.
Three people were killed by the Israeli strikes, according to Syria's health ministry. Israel says it struck a military headquarters and a "military target" near the presidential palace.
Earlier Syria condemned the strikes on Damascus as a "flagrant assault" aiming to "inflame tensions".
It follows days of Israeli attacks on the Suweida region in south-west Syria.
Israel says it is trying to protect members of Syria's Druze community after deadly sectarian clashes - but the strikes have political motive as well as military.
