Thailand's already tense political situation may be poised to worsen, with some analysts saying Thursday's grenade and gun attack may be just the start of a pattern of violence.
"People are almost bracing themselves," said Paul Gambles, managing partner at MBMG International, a personal and corporate advisory. "People are expecting there are going to be a lot more situations to come," he said, noting leaders of the pro-government "Red Shirts" and the anti-government street protestors have been ramping up rhetoric.
The grenade and gun attack on an anti-government protest camp in Bangkok Thursday killed at least three and injured at least 21 people.
Gambles said the Visakha Bucha holiday, often informally referred to as Buddha's Birthday, earlier in the week was likely the reason the violence didn't begin sooner.
The violence is just the latest turn in the country's continuing political deadlock.
Following months of political turmoil, Thailand's Constitutional Court ruled to remove Prime Minister Yingluck Shinawatra last week, along with nine other cabinet ministers. Yingluck was found guilty of abuse of power related to the removal of Thawil Pliensri from the post of National Security Council secretary general in 2011.
