Pakistan marchers threaten Islamabad blockade over Dutch cartoons

Hundreds of far-right protesters are marching on the Pakistani capital Islamabad, threatening to blockade the city unless the country cuts diplomatic ties with the Netherlands over a cartoon competition deemed to be blasphemous.

Protesters belonging to the Tehreek-e-Labbaik Pakistan (TLP) party began the second day of their march on the capital from the eastern city of Lahore on Thursday.

Images from the march showed TLP activists toppling a container used to block their path in the Punjab town of Jhelum, as they continued on their way towards the capital.

Security has been increased in Islamabad ahead of their arrival, with roadblocks prepared to be placed on several major roads.

The TLP activists are protesting against a competition for cartoons depicting Islam's Prophet Muhammad by far-right Dutch opposition leader Geert Wilders, a known provocateur.

Physical depictions of God or the Prophet Muhammad are forbidden in Islam, and the TLP says the competition amounts to "blasphemy".

The Dutch government has distanced itself from the competition, with Prime Minister Mark Rutte clarifying that Wilders is not a member of the government. 

"The competition is not a government initiative," he told a news conference last week.

The Dutch government, however, maintains that banning the competition would be a violation of the right to freedom of expression. 

Foreign Minister Stef Blok echoed Rutte's comments.

"The Netherlands very much adheres by freedom of speech, but we also adhere to treat religions respectfully," Blok said according to Dutch news agency ANP.

He added that the competition "wouldn't be his choice" but that there were no plans to ban the contest from happening.

Wilders leads the Dutch opposition Freedom Party (PVV) and is known for his incendiary speeches and protests against immigration and Islam.

The far-right politician told Dutch media the contest was not being held "to provoke, but to show we are marching for freedom of speech". 

On Tuesday, Dutch police arrested a man accused of plotting to kill the politician over the competition.
