Nearly 40,000 people by Wednesday morning had signed a petition calling for the arrest of Benjamin Netanyahu.

The petition, created on the British Parliament’s E-petitions website that is similar in nature to the US’s, urges lawmakers to arrest the Israeli prime minister for alleged war crimes. The supposed arrest would take place during Netanyahu’s visit to the UK next month.

“Benjamin Netanyahu is to hold talks in London this September. Under international law he should be arrested for war crimes upon arrival in the U.K. for the massacre of over 2,000 civilians in 2014,” reads the petition.

As per British law, the government must respond to all petitions that get more than 10,000 signatures, a similar set up to If a particular petition earns 100,000 signatures, it will be considered for debate in the parliament.

The Israeli Foreign Ministry has called the petition “a public relations stunt with no practical significance.”

“The bilateral relations between Britain and Israel are closer than ever,” the ministry said in a public statement, highlighting data that shows the doubling of trade between the two countries in recent years as well as “fruitful” academic, cultural, and scientific cooperation.
