Five Syrian soldiers were wounded in an Israeli air strike near the western city of Homs early Sunday, Syria's state news agency SANA said.
The strike was Israel's third in recent days after Damascus was targeted on the nights of March 30 and 31, according to the agency.
Syria's air defence intercepted several missiles, but five soldiers were wounded and some material damage was reported, the source added.
The Syrian Observatory for Human Rights, a Britain-based war monitor, said the strikes targeted several military positions of Syrian government forces and pro-Iran groups in Homs.
The NGO said explosions rocked the city and a fire broke out in a research centre, with ambulances heading to the scene of the attack.
Observatory director Rami Abdul Rahman told AFP that in addition to the five wounded Syrian soldiers, several Iranian-affiliated fighters in the research centre had been killed in the strikes.
An officer from Iran's powerful Revolutionary Guards was killed in Israeli strikes in Syria on March 31, a website affiliated with the Guards said.
While Israel rarely comments on the strikes it carries out on Syria, it has repeatedly said it will not allow its arch-foe Iran to extend its footprint in the war-torn country.
