Egypt has warned Hamas against intervening in any potential conflict between Israel and the Lebanon-based terrorist group Hezbollah, Arab media reported on Tuesday.
The heads of Islamic Jihad in the Gaza Strip received a similar warning, the report said.

The warning reportedly followed a statement by a Hamas official to Gaza media, saying that "if war breaks out between Israel and Hezbollah, we will attack on the Gaza border."
Officials in Egypt are furious over the recent rocket fire from Gaza on Israel, which continuously impedes their attempt to broker a ceasefire, a source said.
A Hamas delegation visiting Cairo also received what was said to be a strongly-worded message in which Egypt stated that it would no longer attempt to serve as a mediator between Gaza's rulers and Israel if Hamas continues the barrage of rocket fire on the Jewish state.
According to the Saudi media outlet Al-Arabiya, Hamas denied involvement in the recent rocket attacks, and blamed the other terrorist organizations in the coastal enclave for the escalation, saying that they would like to see hostilities against Israel continue.
According to Arab media reports, Egyptian President Abdel-Fattah el-Sissi is said to be pressuring Hamas to agree to a ceasefire with Israel in exchange for measures designed to alleviate the dire economic situation in Gaza.
