Bomb attack on police kills 11 in Istanbul
A bomb ripped through a Turkish police bus near Istanbul's historic centre Tuesday, killing seven officers and four civilians in the latest of a string of attacks in Turkey's biggest city.
The car bomb targeted a bus shuttle service carrying anti-riot police as it was passing through the central Beyazit district close to many of the city's top tourist sites, Istanbul governor Vasip Sahin said in a statement on Turkish television.
Thirty-six people were wounded, three of them seriously, he added.
The attack had the hallmark of Kurdish militants who have repeatedly targeted the security forces.
Islamic State jihadists have also staged several attacks in Turkish cities in the past year.
There was no immediate claim of responsibility for Tuesday's bombing, which occurred on the second day of the Muslim holy month of Ramadan.
Reports said the explosion took place close to the Vezneciler metro station, which is within walking distance of some of the city's main tourist sites including the famed Suleymaniye Mosque.
The metro station was closed as a security precaution.
The bomb reduced the police vehicle to mangled wreckage and the windows of nearby shops were blown out by the force of the blast.
Television images showed bomb disposal experts examining the scene in case of a second unexploded bomb.
Scheduled examinations at Istanbul University -- which lies close to the scene of the blast -- have been cancelled.
Reports said that shots were heard after the powerful explosion.
The blast took place opposite an upscale hotel favoured by foreign tourists, the Celal Aga Konagi Hotel, a converted Ottoman mansion.
The 16th century Sehzade Mosque -- considered one of the greatest masterpieces of Ottoman architect Mimar Sinan -- was also damaged by the force of the explosion.
Television footage showed its windows blown out and debris littering the floor.
Loudspeakers on mosques were used to warn people to vacate the area, after which a controlled explosion was carried out on a suspicious vehicle.
- Year of attacks -
President Recep Tayyip Erdogan visited an Istanbul hospital where the wounded were being treated.
Prime Minister Binali Yildirim was briefed by Istanbul governor as well as Interior Minister Efkan Ala on "the atrocious terror attack", his office said in a statement.
Foreign Minister Mevlut Cavusoglu, in an interview with state-run TRT television, condemned the attack, saying that Turkey was fighting on all fronts against "any form of terrorism."
There was no immediate indication of who had carried out the attack.
But since the start of the year, Turkey has been hit by a sequence of attacks that have rattled citizens and also caused tourism to plummet.
Two separate blasts in Ankara claimed by the Kurdistan Freedom Falcons (TAK) -- a radical splinter group of the better-known outlawed Kurdistan Workers' Party (PKK) -- earlier this year claimed dozens of lives.
Last month, at least eight people including soldiers were wounded by a remotely detonated car bomb targeting a military vehicle in Istanbul that was claimed by the PKK.
Britain has updated its travel advice for its citizens in the wake of the latest attack, urging them against all but essential travel to the southeast and to remain vigilant in crowded places popular with tourists.
Turkey has stepped up its military campaign against PKK militants in the southeast of the country and in neighbouring Iraq.
Turkish war planes dropped bombs on PKK targets in northern Iraq Monday night, Turkish media reported.
On January 12, a dozen German tourists were killed in a bombing in the heart of Istanbul's tourist district blamed on Islamic State.
Two months later, three Israelis and an Iranian were killed in a bombing on Istanbul's main Istiklal shopping street which was also blamed on IS.
Turkey, a member of NATO and the US-led anti-jihadist coalition, has responded defiantly to the attacks, vowing to overcome both the PKK and Islamic State.
The Kurdish militants have in turn threatened more attacks.
- Tourism industry hit -
The violence has had a devastating effect on the tourism industry, with the latest attack coming at the worst possible time, at the outset of the key summer season.
Some 1.75 million foreigners came to Turkey in April, down more than 28 percent on April 2015, the tourism ministry said in its latest release.
The fall was the steepest monthly decrease for 17 years and raised fresh concerns about the health of the industry.
The US embassy in Turkey in April warned of "credible threats" to tourist areas in Istanbul and the resort city of Antalya, in particular to public squares and docks.
