Anti-government protesters made their presence felt in Thailand's national elections, forcing the closure of some polling stations in 13 of Bangkok’s 33 constituencies, as the country's political crisis deepened.

Voting ended at 08:00 GMT on Sunday but no results will be announced.

Further voting is scheduled for February 23 after problems with advance polling last Sunday, while the ballot in some southern areas may not happen for weeks.

The vast majority of voting stations were open and polling proceeded relatively peacefully, but the risk of violence remained high a day after gun battles in north Bangkok left seven people wounded.
