Germany fears victims in Turkish bombing,Turkish deputy PM says Istanbul suicide bomber is 28-year-old Syrian

German Foreign Minister Frank-Walter Steinmeier has told reporters in Berlin that he cannot rule out that Germans are among the dead in a suicide bombing in Istanbul. He said that the German government is in contact with Turkish authorities and condemned the attack as a "barbaric act of terrorism."

Chancellor Angela Merkel, speaking at a different news conference, said, "we are very concerned that German citizens could be and probably will be among the victims."

Denmark has joined Germany in warning its citizens to avoid crowds outside tourist attractions in Turkey.

The Danish Foreign Ministry updated its website following Tuesday's deadly explosion in a historic district of Istanbul that is popular with tourists, killing at least 10 people and wounding 15 others.

The travel advisory said Danes should "until further notice" avoid public places and other places where a lot of people are gathered.

Turkish Deputy Prime Minister Numan Kurtulmus says the suicide bomber who carried out an attack in Istanbul's historic neighborhood is a 28-year-old Syrian national.

Kurtulmus said most of the 10 people who died in the blast are foreigners. It was unclear whether the number included the alleged bomber.

Kurtulmus was speaking to reporters in Ankara following a high-level security meeting hastily called to discuss the attack. Kurtulmus and other ministers were traveling to Istanbul to oversee the investigation.
