More than 100 of the unauthorised posters were displayed by London Palestine Action to mark “Israeli Apartheid Week”.
Transport for London (TfL) called them an “act of vandalism” and vowed to remove them as quickly as possible, while a Jewish group said the stunt “put strain on inter-community relations” in the capital.
The adverts accused the BBC of pro-Israel bias and condemned G4S-run prisons, the 2014 Gaza war, arms trade and house demolitions.
Activists had hailed a “wave of truth hitting London Underground” on Sunday, dubbing its authentic-looking adverts “subvertisments”.
“Israel and its supporters are used to having the mainstream media repeat their talking points,” London Palestine Action said in a statement.
“We put up around 150 posters on the tube to shine a spotlight on the support Israel gets from the UK: the government, arms industry, and companies like G4S.
“At a time when the government is undermining local democracy to protect Israel, it’s vital to show that we’ll continue to take action in solidarity with the Palestinian popular resistance.”
The stunt came after plans emerged to ban public institutions and councils boycotting products from Israel and the Occupied Palestinian Territories as part of the BDS (Boycott, Divestment and Sanctions) movement.
It prompted the Israeli Prime Minister to instruct the head of his foreign ministry to demand the posters be removed in a meeting with his British counterparts.
Yair Lapid, head of the Yesh Atid party, claimed he spoke to Boris Johnson on the matter and was reassured by the London Mayor that action would be taken, the Jerusalem Post reported.
“The residents of London entered the Underground and found a series of anti-Semitic, anti-Israel signs calling us an apartheid state, accusing us of torturing children, or murder, of terrible things,” Mr Lapid reportedly told a meeting.
“I talked to Johnson, a great friend of Israel, and explained to him that the State of Israel will not tolerate such things.”
The London Jewish Forum accused activists of “seeking to undermine the UK’s relationship with Israel and foster discomfort”.
“These posters are awful smears that do nothing to contribute to peace and dialogue, placing significant strains on inter-community relations across London,” a spokesperson said.
The Israeli Embassy in London confirmed that Mr Netanyahu instructed the director-general of the Israeli Ministry of Foreign Affairs to raise the issue.
“Over the past few weeks we’ve witnessed the ugly side of BDS activism: from vandalism on the tube, to violence at King’s College, to serious allegations of antisemitism at Oxford," a spokesperson said. "When your agenda is based on hatred and divisiveness rather than dialogue, these results are inevitable."
British Transport Police responded to complaints on Twitter on Monday by saying it was working with TfL to “establish the full circumstances”.
Officers were urging people to alert them to the posters’ locations so they could be removed.
A spokesperson for TfL said: “These are not authorised adverts. It is fly posting and therefore an act of vandalism which we take extremely seriously.
“Our staff and contractors are working to immediately remove any found on our network.”
