Pressure mounts on Merkel

A rash of attacks in Germany has emboldened political rivals of Chancellor Angela Merkel, who blamed her liberal asylum policy yesterday for exposing the country to a shocking week of bloodshed.

Four brutal assaults in the south of the country, three of which were carried out by asylum seekers, have rattled Germans and revived a backlash against Merkel's decision last year to open the borders to those fleeing war and persecution.

"It all appeared to be going pretty well for Merkel but the situation has changed dramatically in 10 days between the Nice attack and Sunday's suicide bomber in Ansbach," the daily Sueddeutsche Zeitung wrote, referring to attacks in France and Germany claimed by the Islamic State (IS) group.

"The chancellor must once again fear that she will be punished by the voters," with two pivotal state polls looming in September.

Merkel's aides were quick to point out that three of the four assailants arrived in Germany before the record influx that brought more than one million refugees and migrants last year. The fourth, a teenager who went on a shooting rampage in Munich Friday killing nine before turning the gun on himself, was born and raised in Germany, the son of Iranian asylum seekers who arrived in the country in the 1990s.

The violence reignited political friction that had eased as the number of new arrivals to Germany slowed to a trickle in recent months due to the closure of the Balkans migration route and an EU deal with Turkey to take back migrants.

Seehofer, conservative premier of Bavaria state which saw three of the four attacks, on Tuesday called into question the principle that asylum seekers should never be sent back to war zones.

"We must seriously consider how such people should be treated if they violate the law or can be considered a danger," he told the Muenchner Merkur newspaper.

Merkel, who has led Europe's economic powerhouse for nearly 11 years, sought to project calm by remaining at her holiday cottage north of Berlin this week.
