A rocket and mortar rounds fired from Syria that hit the Israeli-occupied Golan Heights in recent days were not aimed at the Jewish state, an Israeli minister said on Thursday.

"The fire was the result of inter-Syrian fighting and we have no intention of getting involved in that issue," Regional Development Minister Silvan Shalom told Israeli public radio.

International sanctions against Iran over its nuclear program are having an effect, but have not yet convinced Tehran to step back, Israel's deputy foreign minister said on Thursday.

"Iran is on the verge of bankruptcy because of the sanctions, and there are growing protests against the ayatollahs, but these sanctions have not dissuaded the regime in power in Tehran from pursuing its nuclear ambitions," Danny Ayalon told Israeli public radio.

The leaders of Israel and the Palestinian Authority both address the United Nations on Thursday, one seeking recognition for his state, the other warning of a dire threat to his.

One year after Mahmud Abbas made his historic appeal to the U.N. General Assembly for Palestinian statehood, he returned with the more modest goal of seeing his territory given a kind of elevated non-member observer status.

A rocket fired during clashes between Syrian regime forces and rebels exploded on the Israeli-occupied Golan Heights on Wednesday without causing casualties, the military said.

A Greek and a Turkish coastguard vessel have collided in the Aegean Sea, the Greek Foreign Ministry said on Wednesday, adding that a complaint would be made to Ankara over the issue.

The United States on Wednesday slammed "repulsive slurs" against Israel by Iran's President Mahmoud Ahmadinejad and said it would boycott his speech at the U.N. General Assembly.

Ahmadinejad, whose country faces growing pressure over its nuclear program, is one of the most high-profile speakers at the U.N. summit on Wednesday. He has made a series of comments attacking Israel and the West while in New York.

A “tense” meeting held recently between Speaker Nabih Berri and U.N. Special Coordinator for Lebanon Derek Plumbly tackled Lebanon's offshore natural reserves, As Safir newspaper reported on Wednesday.

The two officials discussed the country's exclusive economic zone (EEZ), in which Berri suggested that the 854 square kilometers that Lebanon and Israel are bickering over should be a neutral area.

U.N. leader Ban Ki-moon said Tuesday that the Syrian civil war is a "calamity" that now threatens world peace and demands action by the divided U.N. Security Council.

Ban told the opening of the U.N. General Assembly that the Syria conflict "is a regional calamity with global ramifications" that needs action by the Security Council.

Syrian mortar rounds, apparently fired during fighting between government forces and rebels, fell in Israeli-held territory early on Tuesday, the Israeli military said.

The Israeli army said that an undisclosed number of rounds fell on the Golan Heights, which Israel captured from neighboring Syria in the 1967 Six-Day War and unilaterally annexed in 1981.

Prime Minister Najib Miqati shrugged off fears of Hizbullah's involvement in any future war between Israel and Iran, saying the party is wise and has pledged to steer Lebanon clear of regional conflicts.

“Hizbullah is lately behaving very wisely,” Miqati told reporters in New York. “It has given its consent to the Baabda Declaration that states keeping Lebanon away from the policies of axes and regional and international conflicts.”
