Trump claims Europe attacks prove his 'Muslim ban' right

US president-elect Donald Trump on Wednesday said attacks in Europe this week demonstrated that he is “right” about his controversial plans to instate a Muslim ban.

Trump was speaking about Monday’s assassination of the Russian ambassador to Turkey, an attack on a Christmas market in the German capital Berlin, and a shooting attack on a mosque in Switzerland.   

“You've known my plans all along and I’ve been proven to be right, 100-percent correct,” he told reporters at his Mar-a-Lago estate in Florida, referring to his proposed Muslim ban. “What’s happening is disgraceful.”

Trump described the attack in Berlin, which killed 12 people, as an attack on humanity that needs to be stopped, after on Monday he described it as an Islamist attack on Christianity.

“That’s an attack on humanity, is what it is,” he said. “It’s an attack on humanity and it’s got to be stopped.”

During his campaign, Trump proposed a temporary ban on Muslim immigration to the US and raised the possibility of creating a database to track Muslims living in the country. 

Rights groups have slammed Trump’s plans targeting Muslims, and have vowed to fight them in court.

The Islamic State group took responsibility for the Berlin attack, while German authorities have launched a manhunt for the suspect, who is believed to be a Tunisian citizen who was under covert surveillance for months.

Russia’s ambassador to Turkey was assassinated in Ankara on Monday by a man police say was an off-duty police officer.

The gunman shouted slogans about the Syrian civil war before opening fire.

In Zurich, a gunman wounded three people attending prayer services at mosque. Police have identified the suspect as a Swiss citizen with no links to "radical Islam".
