A drone was downed in a suburb of Damascus on Thursday, the official Syrian news agency SANA reported.
Earlier, explosions were reported in the Jermana suburb southeast of the country's capital.
On Wednesday, drones attacked a company of Iranian-backed Popular Mobilization Forces fighters in Syria, near the Albukamal crossing with Iraq, killing five.
Overnight Monday, there were reports in Iraq of a strike on weapon storage facilities run by militias affiliated with Iran, in the same area of Albukamal. Iraq's Afaq TV attributed the attack to Israel, and the Syrian Observatory for Human Rights said that 10 Iran-backed fighters died.
Last week, twenty-one people were reportedly killed in an explosion at a weapons warehouse used by Iran-affiliated militias in Iraq's Anbar province. Iraqi military sources and reports in Arab media outlets didn't say who was responsible for it, but the incident was linked to recent attacks in the country, some attributed to Israel. The explosion came a day after drones struck Iran-backed militias in eastern Syria, killing at least 18 militia fighters. A Syrian security official said Israeli jets staged the airstrikes, but denied there were any casualties.
Israel, which is alarmed by Iran's growing influence in the region through militia allies in countries including Syria, Iraq and Lebanon, says it has carried out hundreds of strikes in Syria. It wants to stop Iran establishing a permanent military presence there and has struck against advanced weapon shipments to Hezbollah.
Two weeks ago, Hezbollah said it downed an Israeli drone that entered Lebanese airspace. An Israeli military statement said one of its drones "fell inside southern Lebanon during routine operations".
