Israel deported French Palestinian activist Salah Hammouri to France on Sunday, claiming the lawyer has ties to a terrorist group.

The move by the Israeli authorities came despite objections from the French government.

Hammouri's expulsion underscored the fragile status of Palestinians in Israeli-annexed East Jerusalem, where most hold revocable residency rights but are not Israeli citizens.

It also set up a possible diplomatic spat with France, which had repeatedly appealed to Israel not to carry out the expulsion.

"I’m happy to announce that justice was served today and the terrorist Salah Hammouri was deported from Israel," Israel's interior minister, Ayelet Shaked, announced in a videotaped statement. He was set to land in Paris just before 10 a.m. local time.

Hammouri was born in Jerusalem but holds French citizenship.

Israel says Hammouri is an activist in the Popular Front for the Liberation of Palestine, a group that it has labeled a terrorist organization.

He has worked as a lawyer for Adameer, a rights group that assists Palestinian prisoners. Israel has banned the group for alleged ties to the PFLP.

He spent seven years in prison after being convicted in an alleged plot to kill a prominent rabbi but was released in a 2011 prisoner swap with Hamas. He has not been convicted in the latest proceedings against him.

Israel, however, claimed he continued his activities with the banned group, stripped him of residency, and placed him last March in administrative detention – a status that allows Israel to hold suspected militants for months at a time without charging them or putting them on trial.

Hammouri was not charged in the current case, but Shaked ordered the deportation when his detention order expired. Israel’s Supreme Court had rejected an appeal against the decision to revoke Hammouri's residency status.

France's Foreign Ministry condemned Israel's deportation of Hammouri after he landed in Paris, saying it has "taken full action, including at the highest level of the State, to ensure that Mr. Salah Hamouri’s rights are respected, that he benefits from all legal remedies and that he can lead a normal life in Jerusalem, where he was born, resides and wishes to live."

The Israeli human rights group HaMoked, which had defended Hammouri, condemned Sunday's expulsion.

A Jan. 1 hearing on the matter had been scheduled, and it was not immediately clear how Israel was able to push ahead with the deportation.

"Deporting a Palestinian from their homeland for breach of allegiance to the state of Israel is a dangerous precedent and a gross violation of basic rights," said the group's director, Jessica Montell. "HaMoked will continue to fight against this unconstitutional law."

Last year, Hammouri was among six human rights activists whose mobile phones were found by independent security researchers to have been infected with spyware made by the Israeli company NSO Group.

It was not known who placed the spyware on the phones. Israel said there’s no connection between the terror designation of Adameer and five other Palestinian rights groups and any alleged use of NSO spyware. Israel has provided little evidence publicly to support the terrorism designation, which Palestinian groups say is meant to muzzle them and dry up their sources of funding.

Aryeh Deri, Shaked’s apparent successor as interior minister in Benjamin Netanyahu’s new government, said Hammouri’s deportation was "the end of a long but just legal process" and congratulated Shaked for carrying it out.
