A rocket alert siren has gone off in the Israeli-occupied Golan Heights, near the Syrian border.
Residents in northern Israel are reported to have heard several explosions.
The Israeli army has confirmed that "several rockets" struck the area. Israeli media reported that the IDF returned artillery fire towards the positions that launched the rocket attack.
There are no reports of casualties.
IDF spokesman Peter Lerner wrote on Twitter:
Reuters cited Israeli military source saying that two projectiles were fired from Syria and struck the Golan Heights, triggering the warning signals.
The IDF has ordered the Israeli Hermon ski resort to be evacuated following the rocket attack, which comes a week after an Israeli air strike killed six members of Lebanon's Shiite Hezbollah group and one of Iran's senior commanders of the revolutionary guards's corps (IRGC).
The air raid occurred in the Golan Heights near Syria's Quneitra border crossing with Israel.
Israeli police has set up road blocks to prevent people from entering the ski resort area, police spokesman Micky Rosenfeld has confirmed.
