ISTANBUL， Jan. 5 (Xinhua) -- The U.S. embassy in Turkey on Thursday issued a fresh warning after a car bombing attack left four dead earlier in the day in the country's western city of Izmir.


In a statement， the U.S. mission in Ankara advised Americans to stay away from the affected area and other high-frequented places in Turkey.


A policeman at a checkpoint guarding a courthouse in Izmir was trying to stop a car when it exploded， Governor Erol Ayyildiz told the press， saying an exchange of fire erupted after the militants sought to escape.


The policeman and a female usher from the courthouse lost their lives in the gunfight， while two attackers were killed and the third one managed to escape， the governor said.


He put the number of the wounded at seven， three police plus four civilians.


Turkish Prime Minister Binali Yildirim issued a statement asking for unity and praising the dead police officer's effort in preventing more bloodshed.


A second explosive-laden vehicle was defused at the scene， while two automatic rifles， one rocket propelled grenade launcher and eight hand grenades were seized， Ayyildiz said.


The governor， citing initial reports， blamed the Kurdistan Workers' Party outlawed by Ankara for the attack.


Two suspects have been detained over the assault， the state-run Anadolu Agency said.


The bombing attack came in the wake of a shooting attack early Sunday on an Istanbul nightclub that left 39 dead， 25 of them foreigners.


The Islamic State has claimed responsibility for the nightclub carnage， but the gunman remains at large.

Tokyo held its first missile evacuation drill on Monday with volunteers taking cover in subway stations and other underground spaces that would double as shelters for the Japanese capital in the event of a North Korean missile strike.


The choreographed evacuations at a fair ground and park ringing the Tokyo Dome baseball stadium involved around 300 volunteers.


Small groups of protesters scuffled with police as they demonstrated against what they criticized as a war game that fanned public fear.


While hope grows that North Korea's participation in next month's Winter Olympics in South Korea may help defuse tension in the region Authentic Scott Hartnell Jersey , Japan is escalating efforts to prepare its citizens for a possible war.


Tokyo believes the threat posed by Pyongyang's ballistic missile and nuclear weapons development is deepening.


""A missile from North Korea would arrive in less than 10 minutes and the first alert would come about three minutes after launch, which gives us only around five minutes to find shelter,"" Hiroyuku Suenaga Authentic Craig Smith Jersey , a Japanese government official, told volunteers after the Tokyo exercise.


Small Japanese towns and villages have conducted similar drills as North Korea has pushed ahead with its missile and nuclear weapons programs.


North Korea conducted its most recent and biggest nuclear bomb test in September and has tested dozens of ballistic missiles. The latest missile test in November reached an altitude of about 4,475 km (2 Authentic Mattias Ekholm Jersey ,780 miles) and flew 950 km (590 miles), passing over Japan before splashing into waters in Japan's exclusive economic zone.


Pyongyang says its weapons programs are a necessary defense against a possible U.S. invasion.


Amid public concern over the possibility of more missile launches, Japanese public broadcaster NHK issued a false launch alarm urging people to take shelter six days ago. That came days after a similar false alert caused panic across Hawaii.


""I am not that worried about North Korea Authentic Colton Sissons Jersey , if something happened that would be frightening,"" said Hidenobu Kondo, one of the volunteer evacuees. However Samuel Girard Jersey , the 50-year-old company employee said the drill would not be of much use in the event of real attack.


""If I was at work it might be easy to evacuate, but If I was outside somewhere it would be more difficult,"" Kondo said.


Japan's defenses against a ballistic missile strike include Aegis destroyers in the Sea of Japan armed with interceptor missiles designed to destroy warheads in space. PAC-3 Patriot missile batteries represent a last line of defense against warheads that can plunge to their targets at several kilometers per second.


Japan has also decided to buy two land-based Aegis batteries and cruise missiles that could strike North Korean missile sites.

MOSCOW Juuse Saros Jersey , Jan. 22 (Xinhua) -- U.S. President Donald Trump has been forced to make anti-Russian decisions under pressure from his national political opponents, Russian Foreign Minister Sergey Lavrov said Monday in an interview with local media.


""Judging by the personal meeting with U.S. President Donald Trump in the White House, or his meeting with Russian President Vladimir Putin in Hamburg and their telephone conversations Roman Josi Jersey , I did not see Trump undermine his election campaign pledges to restore relations with Moscow,"" Russia's Tass news agency quoted Lavrov as saying.
