LONDON — Emboldened by President Trump’s recognition of Jerusalem as Israel’s capital, Benjamin Netanyahu paid the first visit to the European Union headquarters by an Israeli prime minister in 22 years on Monday, to seek similar endorsement from the 28-nation bloc.

The answer, though, was clear: no.

The bloc’s members are not unified in their attitudes toward Israel, but the EU’s official position is that it supports what Federica Mogherini, its foreign policy chief, called the “international consensus’’ from which Trump departed last week when he announced a reversal of decades of US diplomacy.

The European Union, she said, remains committed to a two-state settlement for the Israelis and the Palestinians, with “Jerusalem as the capital of both.’’ The bloc is the biggest provider of aid to the Palestinians.

Trump’s announcement Wednesday that his administration would break with decades of US foreign policy to recognize Jerusalem as Israel’s capital has sparked protests across the Arab world.

In Lebanon on Monday, thousands of Hezbollah supporters joined a fiery rally in Beirut as the movement’s leader urged Palestinians to rise up after Trump’s decision to recognize Jerusalem.

Demonstrators packed the streets of Beirut’s southern suburbs in a carefully managed march. Crowds chanted, ‘‘Death to America, death to Israel!’’ and waved Palestinian and Hezbollah flags.

The rally followed a violent clash Sunday between police and hundreds of protesters near the US Embassy outside Beirut.

Addressing the crowd Monday via video link, Hezbollah leader Hasan Nasrallah described Trump’s policy change as a ‘‘foolish decision’’ that would mark the ‘‘beginning of the end’’ of the Jewish state.

‘‘The most important response will be to announce a third Palestinian intifada on all occupied Palestinian territories,’’ he said, using an Arabic term that evokes earlier uprisings.

Lebanon has more than 500,000 Palestinian refugees, many of whom fled their homes in what is now Israel and the West Bank during the wars of 1948 and 1967.

During their meeting in London, Netanyahu and European officials referred to White House plans to begin a new effort for peace in the Mideast that is being led by Trump’s advisers, including his son-in-law and senior aide, Jared Kushner.

The Israeli leader also expressed optimism that other countries would follow the US move on Jerusalem.

“I believe that all, or most, of the European countries will move their embassies to Jerusalem, recognize Jerusalem as Israel’s capital, and engage robustly with us for security, prosperity, and peace,’’ Netanyahu said.

Netanyahu met Sunday with President Emmanuel Macron of France in Paris, where he received a taste of what was to come, before flying on to Brussels. France said the status of Jerusalem could only be worked out in a final settlement between Israelis and Palestinians to their decades-old disputes.

After meeting with EU foreign ministers, Netanyahu said recognition of Jerusalem as Israel’s capital “doesn’t obviate peace, it makes peace possible, because recognizing reality is the substance of peace, it’s the foundation of peace.’’

Netanyahu said Trump had simply put ‘‘facts on the table’’ with the recognition of Jerusalem.

In addition to igniting protests in many parts of the Islamic world, Trump’s declaration led to airstrikes on Gaza after Palestinian militants there lobbed missiles into Israel.

The Israeli military said Monday that its planes and tanks again struck Hamas military positions in the Gaza Strip after Palestinian militants fired a rocket toward southern Israel, the Associated Press reported.

The rocket strike was the latest in a series of cross-border exchanges that have left at least four Palestinians dead. No injuries were reported Monday.

It was not clear who fired the rocket, but Israel holds Hamas responsible for all aggressive actions from the Gaza Strip. The militant group also has called for an intifada against Israel in the wake of the Jerusalem announcement.

Netanyahu castigated the European Union over the weekend for what he said was its “hypocrisy’’ in criticizing Trump but not the rocket attacks or incitement against Israel.

Mogherini said she wished to “condemn in the strongest possible way all attacks on Jews everywhere in the world, including in Europe and on Israel and on Israeli citizens.’’

Among the EU members, several smaller countries — including Hungary and the Czech Republic — favor a closer bond with Israel. Last week, the Czech Republic said it would consider moving its embassy from Tel Aviv to Jerusalem but then seemed to retreat, saying it accepted Israel’s sovereignty over only the western part of Jerusalem.

Czech Foreign Minister Lubomir Zaoralek said Monday that Trump’s announcement last week “can’t help us.’’

“I am convinced that it is impossible to ease tension with a unilateral solution,’’ Zaoralek said, according to Reuters, as he and other European foreign ministers gathered for breakfast with Netanyahu. “We are talking about an Israeli state, but at the same time a Palestinian state.’’

French foreign minister Jean-Yves Le Drian said the Europeans had been waiting several months for the new US plan, and were growing weary of waiting.

“If one is not forthcoming,’’ he said, “the European Union will have to take the initiative.’’

Some Israelis, who see a pro-Palestinian bias among many Europeans, have been angered by European moves such as requiring that goods from Israeli settlements in the West Bank be clearly labeled with their provenance.

Additionally, many European countries have been seeking closer ties with Iran since it reached a nuclear deal with the United States and other powers.
