In Syria, Israel has launched hundreds of strikes on military sites since Islamist-led rebels overthrew Bashar al-Assad in December.
Israel says it wants to prevent weapons from falling into the hands of new authorities it considers jihadists.
And despite a ceasefire, Israel has continued to carry out strikes on Lebanon – with both sides repeatedly accusing the other of violating the truce.
Israel launched air strikes on southern Lebanon on Saturday, killing eight people, in response to rocket fire that hit its territory for the first time since a ceasefire took effect on Nov 27.
No party has claimed responsibility for the rocket fire.
The Israeli military has also deployed to the UN-patrolled buffer zone on the Golan Heights, while Prime Minister Benjamin Netanyahu has demanded the demilitarisation of southern Syria.
Syria’s foreign ministry has accused Israel of waging a campaign against “the stability of the country”.
When asked about Israel’s stance towards Syria’s new leaders, Kallas said: “Of course our worries are the same. They say the right things, will they do the right things?”
“But we have discussed this in the European Union and amongst all the member states, and our view is that we need a stable Syria,” she added.
