Britain, Australia, Canada, and Portugal on Sunday formally recognised a Palestinian state, while Belgium and France are set to follow suit at the UN General Assembly; however, many still have not made the move.
Including the four Western nations who announced their decision on Sunday, at least 145 countries out of 193 UN members now recognise the State of Palestine.
Russia, alongside all Arab countries, almost all African and Latin American countries, and most Asian countries, including India and China, are already on the list.
Algeria became the first country to officially recognise a Palestinian state on 15 November 1988, minutes after late Palestine Liberation Organisation (PLO) leader Yasser Arafat unilaterally proclaimed an independent Palestinian state.
Dozens of other countries followed suit in the following weeks and months, and another wave of recognitions came in late 2010 and early 2011.
Israel's war on Gaza has driven 13 countries to recognise the state – a move that has been condemned by Israel and its staunch ally, the United States.
At least 45 countries do not recognise the State of Palestine.
Israeli Prime Minister Benjamin Netanyahu's government completely rejects the idea of a Palestinian state.
In Asia, Japan, South Korea, and Singapore are among the countries that do not recognise Palestine. Neither does Cameroon in Africa, Panama in Latin America, nor most countries in Oceania.
Europe is the most divided continent on the issue and is split almost 50-50 over Palestinian statehood.
Some former Eastern Bloc countries, such as Hungary and the Czech Republic, do not recognise a Palestinian state at a bilateral level.
Western and northern Europe were united in non-recognition until now, except for Sweden, which extended recognition in 2014.
But the war on Gaza has upended things, with Norway, Spain, Ireland, and Slovenia following in Sweden's footsteps to recognise the state in 2024, before the United Kingdom and Portugal did so on Sunday.
Italy and Germany do not plan on recognising a Palestinian state.
