Israel is cooperating with “influential networks” inside Iran, an Iranian parliamentarian said on Sunday amid rising tensions following the July 31 assassination of Hamas political chief Ismail Haniyeh in the Iranian capital, Tehran, Anadolu Agency reports.

“There are networks of influence for Israel in Iran, and there are evil centers in Iran with which the Israelis cooperate and are part of the Mossad’s operations,” Abolfazl Zohrevand, a member of the parliament’s Security Committee, said in statements carried by the Iranian Labor News Agency (ILNA).

Zohrevand, a former diplomat to Afghanistan, criticized what he called inadequate security measures surrounding Haniyeh.

“He (Haniyeh) should have been provided with better and reasonable protection,” he added.

Blaming both Israel and the US for Haniyeh’s assassination, Zohrevand condemned the attack as “a violation of international law.”
