Hundreds of Palestinians in Gaza have demonstrated ahead of US President Donald Trump's expected announcement recognizing Jerusalem as Israel's capital and his plan to move the US Embassy there from Tel Aviv.

The protests were organized by various Palestinian factions and military groups, which are calling for Palestinian unity. Demonstrators waved Palestinian flags and banners declaring Jerusalem to be "our eternal capital." They also burned American and Israeli flags.

Hamas official Salah Bardawil said, "Trump or anyone thinking that our people, nation and resistance are unable to push back his plans is wrong." Hamas' senior political leader Ismail Haniyeh told Al-Jazeera TV that, "our Palestinian people will have a suitable response. As a people, we cannot accept this American pattern."

International condemnation

In an agitated round of calls, the leaders of Saudi Arabia, Egypt, Jordan, the European Union, France, Germany and Turkey have strongly urged Trump against taking this step.

British Prime Minister Theresa May told the House of Commons that Britain's stance is that "the status of Jerusalem should be determined in a negotiated settlement between the Israelis and the Palestinians, and Jerusalem should ultimately form a shared capital. I'm intending to speak to President Trump about this matter."

German Foreign Minister Sigmar Gabriel on Tuesday warned the US about the dangers of moving the US embassy from Tel Aviv to Jerusalem.

"Recognizing Jerusalem as the capital of Israel does not calm a conflict, rather it fuels it even more," Gabriel said. "It's in everyone's interest that this does not happen."

Despite widespread international opposition to the move, Trump is expected to recognize the city as Israel's capital on Wednesday. A senior administration official speaking on the condition of anonymity told AFP news agency that the president would make the announcement during a speech slated for 1 p.m. local time (1800 UTC).

But Trump will reportedly also sign a legal waiver that would delay moving the embassy by another six months.

Palestinian President Mahmoud Abbas said on Tuesday that Trump had called to inform him of plans to move the US embassy, the Palestinian Authority's official news agency reported.

Abbas "warned of the dangerous repercussions of such step on the (long-stalled) peace process, security and stability in the region and the world," said Palestinian presidential spokesman Nabil Abu Rudeineh.

The Jerusalem question

The status of Jerusalem has been a key stumbling block during previous peace negotiations between Israelis and Palestinians, in particular regarding the question of how to divide sovereignty and oversee holy sites. Another major hurdle to peace is illegal Israeli settlements in the West Bank.

The international community has never recognized Jerusalem as Israel's capital or its unilateral annexation of territory around the city's eastern sector, which it captured during the 1967 Six-Day War.

However, Israeli officials have urged the Trump administration to make a decision on the issue. Israeli Defense Minister Avigdor Lieberman called on the White House to take the "historic opportunity" to recognize Jerusalem as Israel's capital, saying he hopes to "see an American embassy here in Jerusalem next week or next month."
