Kosovo was once controlled by the Ottoman Empire and later by the Kingdom of Serbia after the Balkan Wars in the 1910s.
Kosovo is a Serbian and Albanian speaking country and has the majority population of Albanian Muslims and the minority population of Serbs,
Being a part of Yugoslavia from 1946, Yugoslavia recognized the autonomous status of Kosovo with the permission of having a self-government in 1974, but the conflict between the Albanian Muslims, such as Kosovo Liberation Army (KLA) who want to be fully independent, and the minority Serbs, who claimed alleged harassment by the majority Albanian community, kept happening in Kosovo.
In the 1990s when Yugoslavia dissolved, Christian majority countries like Slovenia, Macedonia and Montenegro declared independence from Yugoslavia under Serbian leadership.
On the other hand, Serbia was not happy about the independence of Bosnia that is a Muslim majority country, and Bosnian genocide happened in 1995.
As a response to Kosovo's attempt to become independent in 1999, Serbia also sent troops to Kosovo and started ethnic cleansing, which was stopped by NATO intervention.
Kosovo declared its independence in 2008 with a new constitution that gave political power to the majority Albanian population. While many countries like European countries and the United States recognized the independence, Serbia refused this decision. Russia as a Serbia's ally also used its veto power to prevent Kosovo from getting a seat in the United Nations.
In 2009, new multi-ethnic Kosovo Security Force was formed under NATO that was created to stop the spread of Soviet communism.
In 2013, Kosovo and Serbia agreed to normalize the relationship with assuring autonomy to Serbian minorities in the north of Kosovo.
Under this situation, Kosovo recognized Jerusalem as the capital of Israel in exchange for Israel recognizing Kosovo as an independent country by opening a Kosovo embassy in Jerusalem.
Now it should be easier to understand the recent news.
