Thai capital tense after clashes, 16 dead

Thailand's capital was tense on Saturday after a night of fighting that killed 16 people and wounded 141 as troops struggle to isolate a sprawling encampment of protesters seeking to topple the government.

Thundering grenade explosions and sporadic gunfire echoed across central Bangkok until nearly dawn as the army battled to set up a perimeter around a 3.5 sq-km (1.2 sq-mile) protest site defiant red-shirted demonstrators refuse to leave. (Reuters)
