Israeli helicopters fired several rockets from the Israeli-occupied Golan Heights on targets inside southern Syria, Syrian state media reported on Friday, the latest in what intelligence sources say is an increase of strikes against Iranian-backed militias.
Opposition sources in the area said several militia posts near Quneitra were targeted in the attack, which reports said caused only material damage.
There was no immediate comment from the Israeli army.
Bases and convoys run by Lebanon's Iranian-backed Hezbollah militia, which has a strong presence in the Syrian Golan Heights, have been hit by Israel in recent years.

Israel was stepping up its raids in Syria at a time when world attention and the region, including Syria, was distracted with tackling coronavirus, a regional intelligence source said.
Two weeks ago, an Israeli drone attack targeted a car carrying forces from Hezbollah in southern Syria along the border with Lebanon without causing casualties.
A few days later, Israel struck central Syria near the ancient city of Palmyra, in what regional intelligence sources said were Iranian-backed outposts and a command center.
Israel has acknowledged in recent years it had conducted many raids inside Syria since the start of the civil war in 2011.
After Syria announced last Monday it had intercepted airstrikes by Israel near the capital Damascus, Israeli defence minister Naftali Bennett told Israeli media that Israel would step up its campaign against Iran in Syria.
Bennett appeared to confirm Israel was behind that airstrike on what Western intelligence sources said were Iranian bases.
"We have moved from blocking Iran’s entrenchment in Syria to forcing it out of there, and we will not stop,” Bennett said in a statement.
"We will not allow more strategic threats to grow just across our borders without taking action, We will continue to take the fight to the enemy’s territory,” Bennett said.
The Syrian army later said Monday's strike killed three Syrian civilians and injured several others from shrapnel that hit their homes.
Israel says Iran's military presence in Syria, where its militias are fighting alongside Syrian President Bashar al Assad's forces, is a strategic threat and claims Tehran seeks a permanent presence along its northern borders.
The threat of direct confrontation between arch-enemies Israel and Iran has long simmered in Syria, with Israel regarding Iran as its biggest threat.
Assad has said Iranian forces are welcome to stay in Syria after years of military victories in which Iran and Russian have played a key role in bringing back most of the country back under his control.
