The 67th session of the UN General Assembly continues in New York. At the second day of the session the leaders of Iran, Palestine, Greece, China, Libya, and Iraq addressed representatives of the UN General Assembly.
The main issue discussed during the session was the Iran's nuclear program.
Iran has warned it is ready to retaliate against attack after Israel's prime minister urged a red line to be drawn over its nuclear programme, - BBC reported.
Benjamin Netanyahu told the UN time was running out to stop Iran having enough enriched uranium for a nuclear bomb.
In response, Iran's deputy UN ambassador said his country was strong enough to defend itself.
Israel and Western countries suspect Iran is seeking a nuclear capability. Tehran says its programme is peaceful.
Palestinian President Mahmoud Abbas highlighted the Palestinians' UN status, saying he would continue to seek full membership.
But he said negotiations had begun with "regional organisations and member states" aimed at adopting a resolution making Palestine "a non-member state of the United Nations during this session".
"In our endeavour," he added, "we do not seek to delegitimise an existing state - that is Israel - but rather to assert the state that must be realised - that is Palestine."
Currently, the Palestine Liberation Organisation only has "permanent observer" status. Last year, a bid for full-member status failed because of a lack of support at the UN Security Council.
The change would allow Palestinians to participate in General Assembly debates. It would also improve their chances of joining UN agencies and the International Criminal Court.
Last year, Palestinians joined the UN cultural agency Unesco, despite Israeli and US opposition.
Mr Abbas also denounced Israeli construction in and around East Jerusalem. "It is a campaign of ethnic cleansing against the Palestinian people via the demolition of their homes," he said.
