Dozens of world leaders are gathering in Israel to pay tributes to Shimon Peres, one of the country’s founding fathers, who died on Wednesday aged 93.
Mr Peres’ state funeral will be held in Jerusalem later on Friday.
A massive security operation in preparation has so far led to the “preventative arrests” of several people.
Guests include the Palestinian leader Mahmoud Abbas, who will visit Israel for the first time since 2010.
US President Barack Obama will speak at the ceremony, along with Mr Peres’s three children and the prime minister and president of Israel.
Mr Peres left detailed plans for his own funeral. His body has been lying in state outside parliament in Jerusalem.
From the UK, Prince Charles, Foreign Secretary Boris Johnson and former Prime Minister Tony Blair will attend.
The funeral is expected to be the largest such event in Israel since the funeral of Prime Minister Yitzhak Rabin, who was assassinated by a Jewish nationalist in 1995.
Mr Peres suffered a stroke two weeks ago and died on Wednesday, aged 93, in a hospital near Tel Aviv.
