People from five countries in four different continents have something in common this week -- they're all furious at their governments.

As Kiev continues to burn for the second day, anti-government demonstrators this past week also marched on the streets of Bangkok, Caracas,  Sarajevo and Conakry and clashed with security forces. Here is what you need to understand about why people are protesting in those places.

At least 25 people have been killed and 240 have been injured as violence dramatically escalated between riot police and protesters who opposed President Viktor Yanukovych. Anti-government protesters have been pushing for the government to forge closer ties with Europe and change the government structure so the president does not hold overall power. The latest violence has raised fresh East-West tensions, as Russia has blamed Western countries for failing to condemn the protesters who have attacked police. Although there has been no immediate response from the West, the European Union could impose sanctions that include travel bans targeting the Ukrainian leadership and asset freezes.

Five people were killed and at least 70 have been wounded in clashes between protesters and the police, as the police tried to reclaim official government sites that were occupied by protestors who for months have called for the ouster of Prime Minister Yingluck Sinawatra. Thousands of demonstrators who oppose Sinawatra's government have called for an unelected "people's council," headed by a leader appointed by Thailand's king. The Thai military, which has stayed quiet amid the demonstrations so far, has said it would not hesitate to intervene if violence spiraled out of control.

When Bosnians saw the images of police beating protesters who were demonstrating against the privatization of four factories in the town of Tuzla, they gathered on the streets of Sarajevo, Tuzla and two other towns to protest. Violence escalated soon as police used rubber bullets and tear gas to calm the protesters who started burning down government buildings. The unrest, which is said to be the worst since war ended in 1995, is a result of frustration with the government that had been simmering for quite some time. As the Associated Press notes, the violence is a reflection of economic uncertainty, with a 40-percent unemployment rate, widespread corruption and a widening gap between rich and poor.

Caracas, Venezuela

Protests in Venezuela became violent after security forces killed three demonstrators during a nationwide protests against the government last week. The opposition, led by charismatic U.S.-educated Leopoldo Lopez, has blamed Nicholás Maduro's government of failure, including rising inflation, shortage of basic goods and electricity. Following his speech during a rally on Wednesday, Lopez was arrested by government authorities and may face charges for inciting violence. Maduro has instead placed the blame for economic hardship on the opposition, which he says has conspired with the United States to destabilize his government.

Earlier this week, two people were killed and dozens were injured when protests against power cuts turned violent. Guinea has suffered from frequent water and electricity shortages, and the government led by Mohamed Said Fofana had been asking for more time to fix the power cuts. According to the BBC, despite Guinea's rich mineral wealth, its people are among the poorest living in West Africa.
