Thousands of German protesters take to the streets saying Merkel must go!

Coalition ally withdraws support to open-door immigration policy after terror attacks.

BERLIN, Germany (PNN) - July 31, 2016 - German Chancellor Angela Merkel's premiership is hanging by a thread today as thousands gathered to call for her resignation while a key political ally dramatically withdrew his support over immigration policy.

More than 5,000 protested in Berlin and thousands more throughout Germany over the “open-door” policy that many have blamed for four brutal terrorist attacks over the last month that have left 13 dead. The chancellor faced a fresh wave of fury after it emerged that two recent terror attacks and a third killing were carried out by men who entered the country as refugees.

Despite the massive waves of criticism, Merkel defended her policy this week, dramatically proclaiming “we can do it” as she pledged not to let violent acts guide political decisions.

But now her key ally in Bavaria - which bore the brunt of the attacks - has launched a fresh attack on her leadership, distancing his Party from Merkel and straining the coalition that keeps her in power.

Horst Seehofer, the conservative premier of Bavaria, said he did not share Merkel's “we can do it” credo on accommodating the almost 1.1 million migrants and refugees who arrived in 2015.

Seehofer, who leads the Christian Social Union, the sister Party to Merkel's conservative Christian Democrats, said, "We can do this - I cannot, with the best will, adopt this phrase as my own.”

Speaking after a meeting with the Bavarian government in Tegernsee, he added that the solutions to date were “too inadequate”.

Stressing he had no wish to start a quarrel with Merkel's Party, Seehofer said it was important to look reality in the face.

An axe rampage, a shooting spree, a knife attack, and a suicide bombing in the span of a week stunned Germany, leaving 13 people dead, including three assailants, and dozens wounded.

Three of the four attackers were asylum seekers, and two of the assaults were claimed by the Islamic State group.

“Merkel must go” has been trending on social media, with people posting powerful pictures including one claiming that she has blood on her hands after recent attacks.

The picture shows her splattered with blood, while another depicts her wearing a burka.

A new survey found that 83% of Germans see immigration as their nation's biggest challenge - twice as many as a year ago.

Recent attacks have fueled the right-wing movement, which has long called for stricter immigration controls, particularly in Bavaria, where she faces heavy criticism from high-profile politicians.
