A senior USA intelligence official told the Associated Press that the raids took place with intelligence provided by Washington, a rare example of publicised cooperation between the two countries over choosing targets in Syria.
The strikes, which reportedly targeted more than 15 Iran-linked facilities, were the fourth reported attack by Israel against Iranian targets in Syria in the past two and a half weeks, a significant increase from the normal rate of such strikes.
A senior U.S. intelligence official told The Associated Press that the strikes targeted warehouses used to stage Iranian weapons in Syria.
The official claimed the warehouses also served as a pipeline for components that support Iran's nuclear programme, AP said.

A regional intelligence source said the targets included Syrian security compounds inside Al Bukamal and Deir Zor, while in the past raids had struck only the cities' outskirts. "We're active defensively, politically, and economically", he said. At least 57 fighters were killed and dozens were wounded, according to a Syrian opposition war monitoring group.
Iran's proxy militias led by Lebanon's Hezbollah now hold sway over vast areas in eastern, southern and northwestern Syria, as well as several suburbs around Damascus.
"The warehouses have a control and telecommunications building, and reconnaissance aircraft headquarters".
The daily said Israeli experts, most of whom are former representatives of the Israeli army and intelligence agencies, recommended that Israel be prepared for such a development, adding that pro-Iranian forces will be able to significantly increase the accuracy of their attacks against Israeli positions in 2021.More news: Seahawks fire ex-Jets offensive coordinator Brian Schottenheimer
Israeli warplanes carried out intense airstrikes in eastern Syria early Wednesday, apparently targeting positions and arms depots of Iran-backed forces as the region is on high alert.
Russian media cautioned this week of a possible confrontation between Israel and Iranian forces in southern Syria. The targets included warehouses used to store weapons, according to the report.
Israel rarely comments on strikes in Syria, which it has conducted numerous times in recent years as part of a campaign to counter Iran-linked military presence in the country.
The organization said these were the deadliest airstrikes by Israel since June 2019, when the Israeli military allegedly conducted raids in the same area.
The Observatory said it recorded 39 Israeli strikes inside Syria in 2020 that hit 135 targets, including military posts, warehouses or vehicles.More news: Indiana Guard Troops Going To DC To Aid Biden Security
