On his twitter account the day before the meeting, Israeli Minister in the Prime Minister's Office Ayoub Kara said that Netanyahu and Trump would discuss a plan to establish a Palestinian state in Gaza and the Sinai Peninsula, excluding the West Bank -- reviving an idea long rejected by the international community.

Kara said the two would give their support to the idea, allegedly proposed by Egyptian President Abdel-Fattah El-Sisi.

"This idea was not even a point of discussion during the meeting; everything mentioned in this matter are false claims," Netanyahu said, speaking to reporters in Washington on Thursday. 

The Israeli Prime Minister said his country considers Egypt a key player in the maintenance of security and stability in the region. 

Earlier this week, several international news reports said the staff of Israel's embassy in Cairo had been ordered by Tel-Aviv security services to stay at home due to security concerns.

Both the Egyptian and Israeli foreign ministers declined to comment. 

Israel's Channel 2 television confirmed after these reports that for three months, ambassador David Govrin and his staff have been working from Jerusalem.
