Syrian air defense batteries on Friday intercepted projectiles coming from Israel and downed a number of them, state-owned news agency SANA reported. "Our air defense systems intercepted luminous objects coming from the occupied territories (Israel) and downed several of them," SANA said quoting a military source. Head of Britain-based Syrian Observatory for Human Rights Rami Abdel Rahman said three explosions shook southwest Damascus on Friday. “They were Israeli strikes that targeted the Kiswah region where weapons warehouses belonging to Iran and (its Lebanese proxy) Hezbollah are located,” he told AFP. In April, Syrian air defense intercepted an Israeli air strike targeting Mesyaf in central Hama province, wounding three combatants and destroying buildings, according to SANA. Israel has carried out hundreds of air strikes in Syria, most of them against what it says are Iranian and Hezbollah targets. Israeli shelling recently targeted Aleppo, and in March, Syria announced its air defenses intercepted the Israeli aggression targeting the northeast of the city. On January 21, Israeli fighter jets carried out strikes inside Syria, targeting Iranian facilities and Syrian aerial defense batteries, as well as a site near the Damascus International Airport. The strikes, according to the Observatory, killed 21 people, including members of the Iranian forces and affiliated fighters. Israeli Prime Minister Benjamin Netanyahu vowed during his visit to Chad not to let Iran entrench itself militarily in the war-torn country. In a detailed report, the Observatory said explosions were heard in the vicinity of Damascus, caused by several Israeli missiles where at least three violent explosions took place in the south and south-west of the capital. The flash of one of the explosions was seen in the west of Jaramana, and it was not known whether it was caused by interception by the air defenses to the missiles or the missiles reached their targets in areas in the vicinity of the capital. SOHR noted that the Israeli airstrikes targeted Masyaf area in the western countryside of Hama on the 13th of April, killing several and injuring many others. The Observatory documented the death of at least 14 Iranians and their loyal groups, 9 of which were Syrians and non-Syrians residing on the Syrian territory, while the other 5 include at least 3 Iranians. They were all killed in the Israeli shelling that targeted the Accountant School in Masyaf city, and the mid-range missiles development center in al-Zawi village, and al-Talaee camp in Sheikh Ghadban village in Masyaf countryside. The shelling injured more than 15 others, while the Observatory received information about the killing of Russian and North Korean experts in the Israeli bombardment. On March 28, the Observatory learned that the explosions that rocked the area near Aleppo International Airport and Industrial City in Sheikh Najjar were caused by Israeli raids which targeted ammunition warehouses affiliated with the Iranian forces. SOHR stated in a report that on March 19, violent explosions rocked the suburbs of Damascus, without information so far about the nature of the explosions. The violent sound coincided with firing missiles by the anti-aircraft defenses spread in the suburbs. Earlier in March, an explosion rocked Hodr town in the northern sector of al-Quneitra countryside, caused by at least one rocket shell on an area at the western outskirts of the town, without information about causalities. On February 11, the Observatory recorded an Israeli missile attack targeting Hezbollah and Iranian fighters in the areas of Jubata al-Khashab and al-Quneitra.
