As German politicians continued to bicker on how to deal with the huge refugee influx, American political activist Pamela Geller has issued a new warning that "Islam is coming to take over Germany."

In a report from WND, Geller said what is happening now in Germany and other European countries is a "full-blown invasion" of Muslim militants with ties to the Islamic State (ISIS) jihadist organisation.

Citing her own sources, Geller claimed that 5 million Muslim "invaders" are already in Europe, many of them in Germany, the richest country in the continent.

Last week, she said a Muslim in Germany was caught on video telling a German man: "Islam is coming to take over Germany whether you want it or not ... not through war but by the fact that Germans don't reproduce and Muslims have seven to eight children each ... but not only that, your daughters will marry bearded Muslims and wear the hijab; their sons will wear a beard!

"The Muslims will have four wives and 27 children, and what does the German man have? One child and maybe a little pet dog!

"The German has taken advantage of the Muslim for too long, just so he can drive his Mercedes. ... Now Islam is coming and your daughters will wear the hijab! Ha! I can see the look of hate in your eyes!"

Geller accused the German government led by Chancellor Angela Merkel of putting the lives of its own people at risk for the sake of "big business," contending that "refugee resettlement is big business."

Geller said last week, a number of Germans lost their jobs at the four-star Hotel Maritim which will now be used to house Muslim migrants. Another hotel, the Ramada Hotel Frankfurt/Oder, also faces closure to provide lodging to the migrants.

"Nothing is sacred. They are moving Germans out of their homes to accommodate the invaders," Geller said.

Even churches are being emptied to provide shelter to the hordes of Muslims, she said. "Despite the ongoing harassment of and violence against Middle Eastern Christians by Muslim migrants, these very same migrants are being moved into churches, which necessitates the removal of the altar, the pulpit and the seats," she said.

With their government unable to help or even protect them, German citizens are beginning to take matters into their own hands.

CBS News reported that violence against Muslim asylum seekers spiked over the weekend with police Sunday reporting three different attacks by German nationals on Syrian refugees. Last week, a German national was arrested for killing two migrant children under the age of six.

The report said groups of more than 20 Germans harassed and beat asylum seekers with baseball bats on Saturday in Wismar and Magdeburg.

Several arson attacks were also reported on designated future asylum shelters across Germany, among them an empty hotel in Dresden and a former youth club in Castrop-Rauxel in western Germany, CBS News reported.

Meanwhile as troubles continued to snowball, Reuters reported that Merkel failed on Sunday to fully resolve differences within her ruling coalition over how to deal with the migrant crisis.

The refugee influx has caused a rift in the ruling coalition, with the Bavarian sister party of Merkel's conservative Christian Democrats (CDU) demanding tougher action that many in the third ruling party, the Social Democrats (SPD), oppose, according to Reuters.

Deputy Finance Minister Jens Spahn, a conservative, told Reuters that no society could in the long-run cope with 10,000 migrants arriving a day without controls.

Germany's police chief has already warned that the uncontrolled entry of Muslim migrants poses a domestic security threat to the nation.
