Oil prices have risen over the last 24 hours following Israel's offensive against Palestinian militants in the Gaza Strip, while Israeli stocks and the shekel have weakened, but one analyst told CNBC that markets shouldn't worry unless Iran becomes involved.

On Thursday, Hamas fired dozens of rockets into southern Israel, killing three Israelis in retaliation for the Israel's assassination of Ahmed Al-Jaabari, Hamas' military chief. Israel also launched numerous air strikes across the Gaza Strip and threatened an invasion of the enclave. Iran condemned Israel's attack as "organized terrorism."
