RNA - "Relations with Iran are acceptable but they should further enhance and develop," al-Zahar told FNA on Monday.
Elsewhere, he referred to Israel's recent aggression against the Gaza Strip, and said, "If the regime is after a new war against the region, (it should know that) the Palestinian resistance, more than what they imagine, is ready to enter a real battle and the Zionists have understood this reality well."
In relevant remarks in March, al-Zahar underlined that the Palestinian resistance movement is determined to continue its good relations with Iran.
"The movement is trying to improve its relations with Iran," the Arabic-language Al-Arabi TV quoted Al-Zahar as saying.
Also, in February 2015, senior Hamas official Osama Hamdan stressed that the Palestinian movement would growingly cement ties with Iran.
"Hamas is looking for the expansion of mutual cooperation with Arab and Muslims states as well as those interested in the Palestinian cause across the world, including Iran," Palestine Online news website quoted Hamdan who is in charge of Hamas foreign relations as saying.
He noted that Hamas was trying to improve its relations with Iran, and said, "Hamas has age-old relations with Iran and we want to have constant bilateral ties with Tehran."
