Iranian Supreme Leader Ayatollah Ali Khamenei called on Palestinians on Tuesday to build up their fighting power to stop Israel's "brutality", saying Israelis "only understand the language of force", Iran's state TV reported.
"Zionists understand nothing but the language of force, so the Palestinians must increase their power and resistance to force the criminals to surrender and stop their brutal acts," Ayatollah Khamenei said.
Israel intensified its air strikes on Gaza on Tuesday as rocket barrages hit Israeli towns for a second day in a deepening conflict in which at least 28 people in the Palestinian enclave and two in Israel have been killed.
