Berlin, May 5 (IANS): Germany is increasingly aware of its high risk to Islamist attacks in light of the detention of two extremists who were planning an attack last week, an official said.

Hans-Georg Maassen, head of the Federal Office for the Protection of the Constitution (BfV), noted that the warnings received by German intelligence about potential attacks were "increasingly specific" and "repetitive", Efe news agency reported.

In a press conference during a BfV meeting on Islamist terrorism, Maassen acknowledged that his office receives two or three warnings of potential terrorist attacks every week.

However, he stressed that despite the "high abstract danger" to which Germany was exposed, the interior ministry thinks there was no evidence on the alleged attacks.

Security forces recently reported to the German parliament that there was no concrete indications about a time or a place of any attack, but there remains a general threat due to the country's political and military involvement in Syria and Iraq.

What was obvious, in Maassen's opinion, was that Germany has been "in the focus" of Islamic State and Al Qaeda, which would not, if given the opportunity, hesitate to attack his country.
