WASHINGTON, Feb 19 (Reuters) - Five countries have committed troops for an international security force for Gaza, the commander of the force said on Thursday during a meeting of President Donald Trump's newly created Board of Peace.

"The first five countries have committed troops to serve in the ISF - Indonesia, Morocco, Kazakhstan, Kosovo and Albania. Two countries have committed to train police - Egypt and Jordan," International Stabilization Force commander Army Major General Jasper Jeffers said.

WASHINGTON, Feb 19 (Reuters) - The United States will give the United Nations money to strengthen it and help make it viable, President Donald Trump told the opening meeting of his Board of Peace on Thursday.

The U.S. is the biggest contributor to the U.N. budget, but under the Trump administration it has refused to make mandatory payments to regular and peacekeeping budgets, and slashed voluntary funding to U.N. agencies with their own budgets.

PARIS, Feb 19 (Reuters) - France said on Thursday it was surprised that the European Commission had sent a commissioner to the Board of Peace in Washington saying it did not have the mandate to represent member states, its foreign ministry spokesperson said.

Pascal Confavreux said as far as Paris was concerned, the Board of Peace needed to recentre to focus on Gaza in line with a United Nations Security Council resolution and that until that ambiguity was lifted, France would not take part.

WASHINGTON, Feb 19 (Reuters) - U.S. President Donald Trump said on Thursday that various U.S. allies have contributed over $7 billion to relief efforts in Gaza.

Speaking to the initial meeting of the Board of Peace, which Trump created, the U.S. president said that it looks like Palestinian militant group Hamas will disarm.

WASHINGTON, Feb 19 (Reuters) - President Donald Trump said on Thursday that the United States had to make a meaningful deal with Iran, citing good talks with the Middle Eastern country.

"Good talks are being had. It's proven to be, over the years, not easy to make a meaningful deal with Iran. We have to make a meaningful deal, otherwise bad things happen," Trump told the first meeting of his Board of Peace in Washington.

JERUSALEM/CAIRO, Feb 19 (Reuters) - A U.S.-backed Palestinian committee established to take over the civil administration of Gaza opened applications for a police force for the strip on Thursday, ahead of the inaugural meeting of President Donald Trump's Board of Peace.

Trump is expected to announce a multi-billion-dollar reconstruction plan for Gaza and detail plans for a U.N.-authorized stabilization force for the Palestinian enclave at the meeting in Washington. Establishing security in Gaza is one of many formidable hurdles.

US President Donald Trump said on Thursday that Iran must make a "meaningful deal" in negotiations with Washington in the next 10 days or else "bad things happen", as he deployed warships, fighter jets and other military hardware to the region.

"It's proven to be over the years not easy to make a meaningful deal with Iran. We have to make a meaningful deal otherwise bad things happen," Trump told the inaugural meeting of the "Board of Peace", his initiative to secure stability in Gaza.

DUBAI, Feb 19 (Reuters) - Russia warned against an "unprecedented escalation of tension" around Iran on Thursday and urged restraint amid a U.S. military build-up in the region that a senior American official said should be complete by mid-March.

U.S. threats to bomb Iran, with the two sides far apart in talks on Tehran's nuclear programme, have pushed up oil prices and a Russian corvette on Thursday joined planned Iranian naval drills in the Gulf of Oman, a vital sea route for global energy.

GENEVA, Feb 19 (Reuters) - Israeli forces, Hamas and other Palestinian armed groups have both committed serious violations of international humanitarian law in Gaza and carried out atrocity crimes, a U.N. report published on Thursday said.

Intensified Israeli attacks and the forcible transfer of Palestinians appeared aimed at a permanent demographic shift in Gaza "raising concerns over ethnic cleansing," the report by the U.N. human rights office said.

The head of Doctors Without Borders in the Palestinian territories told AFP the charity would continue working in Gaza for as long as possible, following an Israeli decision to end its activities there.

In early February, Israel announced it was terminating all the activities in Gaza by the medical charity, known by its French acronym MSF, after it failed to provide a list of its Palestinian staff.

MSF has slammed the move, which takes effect on March 1, as a "pretext" to obstruct aid.
