THE Islamic State group has claimed responsibility for a suicide attack in Ansbach, Germany that wounded 15.
The Aamaq news agency that is linked to IS said the attack was carried out by "one of the soldiers of the Islamic State."
Aamaq said on Monday that the man carried out the attack in response to calls by the group to target countries of the US-led coalition.
Authorities say a failed asylum-seeker from Syria blew himself up and wounded 15 people on Sunday after being turned away from an open-air music festival in southern Germany.
It was the fourth attack to shake Germany in a week - three of them carried out by recent migrants.
A European Union spokesman has acknowledged "serious loopholes" in the bloc's current rules on the acquisition and possession of firearms, but said the EU's executive has submitted proposals for tighter regulation.
Germany's vice-chancellor called for tightened gun laws following last Friday's shooting spree in Munich in which an 18-year-old gunman who is believed to have purchased his firearm illegally on the internet killed nine people as well as himself.
If adopted, the EU Commission's package of proposals will "make it more difficult to acquire firearms in the European Union, allow to better track legally held firearms and strengthen the cooperation between all member states," EU spokesman Ricardo Cardoso said.
The Commission, the EU's executive arm, issued the proposals in November, and they are now under consideration by the European Parliament and the governments of the EU's 28 member countries, said Mr Cardoso.
The chief EU spokesman, Margaritis Schinas, said the bloc continues to keep the door open for people seeking asylum from war and persecution, but that Europeans must also defend themselves against attacks on their way of life.
Bavaria's top security official has said a video has been found on the Ansbach bomber's phone showing him pledging allegiance to the leader of the Islamic State group.
Joachim Herrmann said that according to an initial translation of the Arabic-language video the 27-year-old man announced a "revenge" attack against Germany.
Mr Herrmann told reporters the video strongly suggests the bombing was a "terrorist attack".
Officials also said police found violent videos and bomb-making material at his home.
Mr Herrmann said officers discovered videos with "Salafist content" on storage devices seized at the Syrian man's home.
He told reporters police also found gasoline, chemicals and other material that could be used to make a bomb.
The unnamed Syrian was the only person killed in the blast. More than a dozen people were wounded.
