The Kurdish-led Syrian Democratic Forces alliance stated the Turkish raids targeted pro-government positions, but gave no death toll, AFP said.
The Britain-based Syrian Observatory for Human Rights said the strikes on the area of Kafr Janna were the third such raid on loyalist fighters in the enclave bordering Turkey in less than 48 hours.
They came after Turkish raids on other parts of the enclave killed 14 pro-Damascus fighters on Thursday and four more on Friday, the monitor said.
Turkish-led Syrian opposition fighters have advanced steadily since January 20 when they launched an assault on Afrin, controlled by the Kurdish People's Protection Units (YPG).
The Syrian government deployed fighters to the enclave a month later after the Kurds appealed for help.
The Observatory says Turkish-led forces control more than 20 percent of the enclave after seizing the area of Rajo in the northwest of Afrin on Saturday.
They also seized a strategic mountain in the northeast of the enclave, a military official from the Turkish-led operation said.
