GENEVA (Reuters) -The United States and Israel have sent complaint letters to top U.N. officials contesting the impartiality of their staff over the Gaza war, documents showed, as hundreds of U.N. staff protested outside its European headquarters on Thursday.

U.N. staff carried placards saying "Peace for Gaza" and "Not a Target". They laid over 370 white roses next to a memorial plaque in Geneva to represent each U.N. aid worker killed in the nearly two-year war.

THE HAGUE (Reuters) -A United Nations Commission of Inquiry concluded this week that Israel has committed genocide in Gaza. Israel dismissed the findings as biased and based on unverified evidence.

Below is an explanation of how genocide is defined legally, how it is tried by the courts, and how the U.N. inquiry reached its findings.

WHAT IS GENOCIDE?

(Reuters) - Two Israelis were killed on Thursday in what Israel's military described as a 'terror attack' at Allenby Crossing, the only gateway for Palestinians from the Israeli-occupied West Bank to Jordan.

The Israeli ambulance service said the two men succumbed to their wounds, while the shooter was killed by security forces.

The Israeli military later said it had killed a "terrorist" at the scene who arrived in a truck transporting humanitarian aid from Jordan and opened fire.

Jordan's government spokesperson said authorities were following up on the incident.

CAIRO (Reuters) -Israeli tanks were seen in two Gaza City areas that are gateways to the city centre, residents said on Thursday, while internet and phone lines were cut off across the Gaza Strip, a sign that ground operations were likely to escalate imminently.

Israeli forces control Gaza City's eastern suburbs and in recent days have been pounding the Sheikh Radwan and Tel Al-Hawa areas, from where they would be positioned to advance on central and western areas where most of the population is sheltering.

Israeli tanks and jets pounded Gaza City, the target of a major ground offensive, on Thursday prompting Palestinians to flee south, where the Israeli military announced the deaths of four soldiers.

AFP journalists and witnesses saw a steady stream of Gazans heading south on foot, in vehicles and on donkey carts -- their meagre belongings piled high.

"There is artillery fire, air strikes, quadcopter and drone gunfire. The bombing never stops," said Aya Ahmed, 32, sheltering with 13 relatives in Gaza City.

BERLIN (Reuters) -The European Union must look to trade deals with countries like India to reduce dependencies, with higher U.S. import tariffs pushing the bloc to diversity its ties, European Commission President Ursula von der Leyen said on Thursday.

"We want to make a deal with India this year," von der Leyen said at a conference with German business leaders, adding that Indian Prime Minister Narendra Modi had assured her of his commitment to this goal in a phone call on Wednesday.
