Bangkok: Twin blasts in a seaside resort town in Thailand killed one and injured 19 others, including foreigners, late Thursday, the latest explosions in the region's top tourist destination.
Small bomb attacks are common in Thailand during times of heightened political tension, but there have been few such incidents in the past year and it is rare for tourists -- a key source of income for the kingdom -- to be targeted.
Unrest is often attributed to disputes over business, local politics or criminal activities.
Bangkok has been hit by several explosions in recent years, including a blast at a shrine in an area popular among tourists that left 20 people dead almost one year ago, the deadliest attack in Thailand.
Thai officials said they are investigating the motives behind the latest explosions, which took place near the bar district in Hua Hin, popular among foreign and local tourists.
Here is a brief timeline of some blasts in Thailand in recent years.
2010
July: A suspected bomb rips through a bus stop in central Bangkok, leaving at least nine people injured and reigniting tensions two months after the end of opposition protests.
October: A blast at a Bangkok apartment complex kills four, with the government blaming the incident on the anti-government "Red Shirt" movement, which denies any involvement.
2011
December: A makeshift explosive device is found and defused near the government lottery office in the capital with authorities saying the perpetrators wanted to "challenge the government".
2012
February: A string of botched blasts across Bangkok injure several people in an alleged plot by Iranian suspects to kill Israeli diplomats. Two Iranian men, including one whose legs were blown off, were sentenced to between 15 years and life in 2013 over the failed plot.
