Lebanon's Iran-backed Hezbollah movement on Friday said it would be "fully prepared" to join Hamas in the war against Israel when the time is right. 

"We are fully prepared, and when the time comes for action, we will carry it out," Hezbollah deputy chief Naim Qassem told a pro-Palestinian rally in Beirut's southern suburbs.

He said that major powers, Arab countries and the United Nations had "directly and indirectly" told Hezbollah "not to interfere" in ongoing fighting between Israel and Hamas.
