Iran reiterated its support for Palestinian resistance against Israel on Friday, saying that it would "use everything at its disposal" to support the Palestinians, according to an AFP report.

First vice-president Mohammad Reza Rahimi made the remarks to leader of Hamas in the Gaza Strip Ismail Haniyeh, who is in the country on a three-day visit, AFP cited Iran's presidential website as saying.

"Iran will not retreat one iota from its position on defending the rights of the Palestinian people," Rahimi was cited as saying. Iran "will use everything at its disposal to support the oppressed Palestinians," he said, adding, "The Palestinian issue is a red line for us."

The presidential website also quoted Rahimi as saying that "soon the Zionist regime will be punished for its plots and aggression," AFP said.

Haniyeh arrived in Tehran for the visit on Friday. According to media reports, Haniyeh will meet with Supreme Leader Ayatollah Ali Khamenei, President Mahmoud Ahmadinejad and other senior officials. There were also reports that he would receive an honorary degree from Tehran University, AFP said.

Haniyeh left on Monday for a tour of Iran and Gulf states, continuing a diplomatic drive to realign the Palestinian Islamist movement after a year of political change in the Arab world.
