A West Yorkshire teacher has been suspended after reportedly showing an “offensive” caricature of the Prophet Mohammed during a religious studies lesson, sparking a protest outside the school.

Protesters had gathered outside Batley Grammar School, near Bradford, on Thursday, following claims a member of staff had shown students a cartoon deemed offensive to the Islamic faith.

Pictures circulating on social media earlier in the day showed dozens of people stood outside the school gates, partially blocking the road.

The school has “unequivocally” apologised for showing “totally inappropriate” material to children and said a member of staff has been suspended pending an investigation.

Dr Abdul Shaikh, a local academic in Batley and Muslim activist, said he had heard about the incident on social media on Wednesday night.

Speaking to the PA news agency, he said: “I was shocked like many Muslims in the town that Muslim school children’s religious sensitivities were completely ignored by the school teacher who decided to show an offensive image that lampooned the noble Prophet Mohammed.

“Every Muslim around the world holds the Prophet in the highest esteem.

“I feel that the school should be allowed to complete their investigation in due course and find a fair and adequate solution that satisfies first and foremost Muslim pupils, their parents and the wider Muslim community in Batley.

“This situation should not be allowed to happen again for the sake of community cohesion in the area.”

West Yorkshire Police said they were called to the protest at around 7.30am on Thursday.

A police spokesman said the school road had been closed for a short time, no arrests were made and no fines were issued.

In a statement, Batley Grammar School head teacher Gary Kibble said: “The school unequivocally apologises for using a totally inappropriate resource in a recent religious studies lesson.

“The member of staff has also given their most sincere apologies.

“We have immediately withdrawn teaching on this part of the course and we are reviewing how we go forward with the support of all the communities represented in our school.

“It is important for children to learn about faiths and beliefs, but this must be done in a sensitive way.

“The member of staff has been suspended pending an independent formal investigation.”

In a letter addressed to Mr Kibble and shared online, founder of Batley-based charity Purpose Of Life, Mohammad Sajad Hussain, said he was “deeply hurt” by the “insulting caricatures of our beloved Prophet Mohammed”.

He said the charity is unwilling to work with or promote the school until the teacher is “permanently removed”.

However, the National Secular Society branded the protest as an “attempt to impose an Islamic blasphemy taboo on a school”.

Stephen Evans, chief executive of the National Secular Society, said: “Teachers must have a reasonable degree of freedom to explore sensitive subjects and enable students to think critically about them.

“And the school’s weak response will fuel a climate of censorship, which is brought on by attempts to force society as a whole to accommodate unreasonable and reactionary religious views.”

An Islamist party in Pakistan called for the expulsion of the Dutch ambassador on Wednesday as it launched a protest against a far-right Dutch politician’s plan for a cartoon competition featuring caricatures of the Muslim Prophet Mohammed.

Several thousand activists gathered in the eastern city of Lahore for the demonstration organised by Tehreek-e-Labbaik, a party that amassed the fifth largest number of votes in a general election last month having campaigned as a defender of the laws and punishments for crimes of blasphemy.

Party leader Khadim Hussain Rizvi set out from Lahore’s historic centre at the head of a protest he aims to take through the towns of Punjab province to the capital Islamabad, where protesters will stage a sit-in to pressure Pakistan’s new Prime Minister Imran Khan to cut diplomatic ties with the Netherlands.

“The Dutch ambassador should be immediately deported,” Labbaik spokesman Ejaz Ashrafi told Reuters. “We will only stop when the government meets this demand.”

Pakistan has already complained to the Dutch government about far-right parliamentarian Geert Wilders’ plans for a cartoon contest that will upset and provoke Muslims.

Wilders intends to display the cartoons on the walls of his political party’s room in parliament. He says he’s had “hundreds” of entries.

“The Foreign Office called the chargé d’affaires of the Netherlands and issued him a Demarche’ to record a protest,” the Pakistani prime minister’s office said in a statement on Wednesday.

The Netherlands Prime Minister Mark Rutte said last week that the cartoon competition “was not something I would do” and his government was not associated with it.

Pakistan’s Foreign Minister Shah Mehmood Qureshi said he planned to take up the issue with the United Nations and several world leaders.

“They don’t understand how much they hurt us when they do such acts,” Khan, a cricketer-turned-politician, said on Tuesday, a day after the upper house of parliament condemned the proposed cartoon competition.

Officials from the Punjab provincial government met with Labbaik leaders in Lahore in a vain attempt to persuade them to call off their protest.

“We told them to stop the protests because the Pakistan government is taking up the issue effectively,” an official involved on the talks told Reuters, adding that Labbaik representatives insisted the protest would only end once the Dutch envoy was expelled.

Last year, in a stand-off with the previous government, Labbaik shut down a main highway leading into Islamabad for nearly three weeks over a small change in wording to an electoral law changing a religious oath to a simple declaration. Labbaik said the change amounted to blasphemy.

The ruling Pakistan Muslim League-Nawaz was forced to accept the resignation of law minister Zahid Hamid, who Labbaik held responsible for the change, after seven people were killed and nearly 200 wounded in a failed attempt by police to disperse protesters.

A relative of one of the militants who attacked French satirical magazine Charlie Hebdo in Paris in January 2015 has been put under formal investigation for Islamist ties and remanded in custody, a judicial source said on Saturday.

The source said Mourad Hamyd was suspected of trying to travel to Syria to join Islamic State.

Hamyd, who is French and a brother-in-law of assailant Cherif Kouachi, was detained in Bulgaria last month after a Paris court issued a European arrest warrant against him.

Hamyd was questioned by French police following the Charlie Hebdo attacks in which Cherif Kouachi and his brother Said shot dead 12 people before being killed by police, but was cleared of any involvement.
