Bangkok - A bomb blast early Tuesday at a Bangkok airport occupied by anti-government demonstrators killed one person, protestors said.

The explosion at Don Mueang Airport set off panic in the occupied terminal building, where 22 people were wounded by flying glass caused by the device, the Thai newspaper Nation reported on its website.

The airport has been occupied, preventing flights, since Thursday by protestors demanding the ouster of the current government.

Several grenade blasts have occurred in recent weeks at demonstrations by the opposition group PAD. No suspects have been charged in the previous attacks. (dpa)
