11:12 a.m. ET -- Speaking about the Palestinian issue, Gul said "the denial of the right of the Palestinians to have a state of their own has no justification on any moral, political, or legal grounds." "We therefore welcome and strongly support the talks initiated between the parties under the auspices of the United States. The success of future efforts mainly depends on the Israeli government's acceptance of the establishment of a viable, contiguous Palestinian state."
11:08 a.m. ET -- Tweets from Ivan Watson, @IvanCNN: "Turkish President Gul at UNGA: 'we must realize that inaction by the security council only emboldens aggressive regimes.' " ...

Turkish President Gul at UNGA:"we must realize that inaction by the security council only emboldens aggressive regimes."
11:07 a.m. ET -- "I cannot emphasize this enough," Gul said: "Agreement on chemical weapons must not be allowed to substitute for a comprehensive political strategy to address the situation in Syria."
11:05 a.m. ET -- Gul addressed Syria's chemical weapons. "Turkey welcomes and firmly supports the U.S.-Russian agreement to eliminate Syria's arsenal of chemical weapons," but he stressed that the "agreement has to be translated into a tangible U.N. Security Council resolution." "Once Syria comes clean about this arsenal, once and for all, it will be a relief for the Syrian people and the region."
10:59 a.m. ET -- The issue of Syria is all-important to Turkey, and Turkish President Abdullah Gul is expected to address the Syrian civil war.
10:59 a.m. ET -- Next up: Turkish President Abdullah Gul.
10:58 a.m. ET -- And that's it from Obama. Just a few highlights here: He said he was ready to use "all elements of U.S. power," including military force, to protect U.S. interests in the Middle East. He's encouraged that Iranian "President Rouhani received from the Iranian people a mandate to pursue a more moderate course," and he's directing his secretary of state to pursue a nuclear agreement with Iran. And he said that U.S. disengagement from the Middle East would create a vacuum of leadership.
10:49-10:51 a.m. ET -- Tweets from @jimsciuttoCNN: "Biggest news of Obama #UNGA speech: his directing @JohnKerry to pursue nuclear deal with #iran . Huge investment of capital" ... "Obama on #Iran : 'conciliatory words must be matched by actions that are transparent and verifiable' " ... "President Obama: US-Iranian "mistrust has deep roots" #UNGA" ... "@MeetIran @HassanRouhani @JZarif when is last time so many Iranian officials stayed for US president speech?"
10:48 a.m. ET -- Obama supported the action in Libya, where the U.N. Security Council "provided a mandate to protect civilians" and "America joined a coalition that took action." "Does anyone truly believe that the situation in Libya would be better if (former Libyan leader Moammar) Gadhafi had been allowed to kill, imprison or brutalize his people into submission? It is far more likely that without international action, Libya would now be engulfed in civil war and bloodshed."
10:48 a.m. ET -- Tweet from @eliselabottcnn: "Obama: US may have limited influence, be accused of hypocracy (ie #bahrain , #syria ), but US will be engaged in #mideast for long haul #unga."
10:48 a.m. ET -- Tweet from @eliselabottcnn: "Obama: on #egypt ; shows US will work with govt it doesn't agree with if it helps US security interests but won't give up principles. #unga."
10:45 a.m. ET -- Obama said it is important for the United States to remain engaged in North Africa and the Middle East. "I believe that such disengagement would be a mistake. I believe America must remain engaged for our own security," but also because "I believe the world is better for it," he said.
10:42 a.m. ET -- Obama is now talking about Egypt, where longtime ruler Hosni Mubarak was ousted in 2011 and President Mohamed Morsy was ousted this summer. The United States' overriding interest regarding Egypt these past few years has been to encourage the existence an Egyptian government that legitimately reflects the will of the people, but respects minority rights and freedom of assembly, Obama said.
10:41 a.m. ET -- Obama addressed Egypt, saying U.S. support for that country will depend upon that nation's "progress in pursuing a democratic path." "Our approach to Egypt reflects a larger point: The United States will at times work with governments that do not meet the highest international expectations, but who work with us on our core interests. But we will not stop asserting principles that are consistent with our ideals, whether that means opposing the use of violence as a means of suppressing dissent, or supporting the principles embodied in the Universal Declaration of Human Rights."
10:39 a.m. ET -- A quick look back at what he said about Iran: "We are encouraged," Obama said, "that President Rouhani received from the Iranian people a mandate to pursue a more moderate course. Given President Rouhani's stated commitment to reach an agreement, I am directing John Kerry to pursue this effort with the Iranian government, in close coordination with the European Union, the United Kingdom, France, Germany, Russia and China." "The roadblocks may prove to be too great, but I firmly believe the diplomatic path must be tested."
10:38 a.m. ET -- President Obama says the United States is "determined to prevent" Iran "from developing a nuclear weapon" but said diplomacy "must be tested." "We should be able to achieve a resolution that respects the rights of the Iranian people, while giving the world confidence that the Iranian program is peaceful. To succeed, conciliatory words will have to be matched by actions that are transparent and verifiable," he said.
10:37 a.m. ET -- Obama said "real breakthroughs" on Iran's nuclear program and Israeli-Palestinian peace "would have a profound and positive impact on the entire Middle East and North Africa."
10:36 a.m. ET -- Adding to what he said about the Israeli-Palestinian issue: "The occupation of the West Bank is tearing at the democratic fabric of the Jewish state." But Israelis have the right to live in a world that recognizes their right to live in security, he said: "The state of Israel is here to stay."
10:36 a.m. ET -- The United States, he said, "remains committed to the belief that the Palestinian people have a right to live with security and dignity in their own sovereign state."
10:33 a.m. ET -- Talking about the Israeli-Palestinian issue, Obama underscored his support for Israel. "I have made clear that the United States will never compromise our commitment to Israel's security, nor our support for its existence as a Jewish state."
10:31 a.m. ET -- Tweet from @RafaelRomoCNN: #Obama : "The US is chastised for [both] meddling in the [Middle East] region... and failing to do enough." #UNGA @CNNLive
