Dubai police have foiled a bid to smuggle 16,000 guns from Turkey to Yemen's northern province of Saada, the stronghold of Shiite rebels, the Gulf emirate's police chief said on Thursday.

Six Arab residents of the United Arab Emirates of which Dubai is a member have been arrested as "police foiled a major attempt to smuggle arms from Turkey to Yemen," Lieutenant General Dahi Khalfan told a press conference.

One person was killed and more than 30 were wounded when a bomb ripped through a bus in Jerusalem on Wednesday, just hours after Palestinian factions vowed revenge for two deadly Israeli raids on Gaza.

The bombing came several hours after two Grad rockets fired by militants in Gaza had slammed into the southern city of Beersheva, prompting Israel's Benjamin Netanyahu to warn that anyone who attacks the Jewish state would learn it has an "iron will" to defend itself.

Twenty people were hurt, three of them seriously, when a bomb exploded next to a bus in Jerusalem, medics said, after Gazan militants threatened retaliation for a series of deadly Israel raids.

"The bomb was inside a bag which was left at the bus stop," Israel's Internal Security Minister Yitzhak Aharonovitch told reporters at the scene.

NATO will not take "political leadership" of the international coalition in Libya but will have a planning and operational role to enforce a U.N.-backed no-fly zone, the French foreign minister said Wednesday.

"NATO will intervene as a tool for planning and operational action" in applying the no-fly zone provided for in U.N. Security Council Resolution 1973, Alain Juppe said at a press conference.

Bahraini airlines have suspended flights to Iran, Iraq and Lebanon, where Shiite communities have criticized the kingdom's response to Shiite-led protests in the Gulf state, the airlines said Wednesday.

On Friday, Bahrain carried out a bloody crackdown on pro-democracy activists demonstrating since February 14 in the tiny Shiite-majority, Sunni-ruled kingdom.

The situation in Bahrain is at a "very dangerous stage" Bahrain Foreign Minister Sheikh Khaled bin Ahmad Al-Khalifa told Turkish TV channel NTV Wednesday.

"What is happening in Bahrain is now at a very dangerous stage. There is stability but, we are absolutely afraid of the division between religious communities," Al-Khalifa told in an interview with over-voice translation. Al-Khalifa said Turkey and Bahrain should have a common policy on the division between religious communities in the Islamic world.

Egypt's stock exchange on Wednesday plummeted nearly 10% after reopening for the first time since January 27 at the start of an uprising that brought down long-time president Hosni Mubarak.

Yemeni MPs on Wednesday approved a state of emergency declared by President Ali Abdullah Saleh who faces escalating demands for his ouster.

Gaza militants fired seven mortar shells into southern Israel early on Wednesday, just hours after they fired a Grad rocket into the heart of the southern city of Beersheva, the army said.
