On June 24, Israel's military said it launched a Patriot missile at an incoming unmanned aerial vehicle, which turned away unharmed.
Israeli forces attacked Syrian regime military positions near the Golan Heights border in the early hours of Thursday, causing limited damage, Syrian state media said.
The drone shot down by the IDF was an intelligence-gathering aircraft and belonged to the Syrian government and its remains have already been retrieved just south of the Sea of Galilee, nearly ten kilometers (six miles) inside Israel, an army spokesman told reporters.
"The IDF will continue to operate determinedly and decisively against any attempts to hurt Israeli civilians and breaches of Israeli sovereignty".
Rocket sirens triggered in the Golan Heights and Jordan Valley, the IDF said.

"We are still looking into why it crossed, whether it was on a military mission and crossed on objective, or it strayed", said Lt Col Jonathan Conricus, an Israeli military spokesman.
According to Haaretz, the drone was tracked after it went about 6 miles into Israeli territory.
Israel threatened a "harsh response" on Monday to any attempt by Syrian forces advancing against southern rebel areas to deploy in a Golan Heights frontier zone that was demilitarized under a 44-year-old United Nations monitored truce between the neighboring foes.
In the heaviest Israeli firing since the start of the Syrian War, the UK-based Syrian Observatory for Human Rights, said the strikes killed at least 23 military personnel, including Syrians and non-Syrians.
While the Russian and Israeli leaders sat down for talks in the Kremlin, a senior Iranian envoy also headed to Moscow amid intensive Syria-focused diplomatic efforts ahead of Putin's summit in Helsinki on Monday with President Donald Trump.
The Israeli official who requested anonymity said Russian Federation was working to distance Iranian forces from the Golan and had proposed that they be kept 80 km (50 miles) away but that this fell short of Israel's demand for their full exit along with that of Tehran-sponsored militias.
The IDF soon confirmed targeting sites in Syria, claiming it was their response to a drone infiltration earlier on Wednesday. Israel captured much of the strategic plateau in the 1967 war with Syria and annexed it in a move not recognised internationally.
"We will discuss Syria, we will discuss Iran, we will discuss Israel's security needs", Netanyahu told reporters before departing.
