Two anti-government protesters are reported to have been killed and 22 others injured in an attack in Bangkok.

Witnesses reported explosions and gunfire at a protest camp at the city’s Democracy Monument, according to the BBC.

Protesters have been pressing the Senate to replace the cabinet with an appointed administration.

It comes after former prime minister Yingluck Shinawatra was removed by a Thai court last week.

Both pro and anti-government groups have held rallies in the Thai capital, raising fears of further violence.

Reports said grenades were thrown in the latest attack early on Thursday, followed by gunfire. A doctor at an emergency centre in Bangkok said the wounded had been hit by shrapnel.

“The first victim was a protester who was sleeping at Democracy Monument, while the second was a protest guard who died from gunshots,” police Major Wallop Prathummuang told the AFP news agency.

Thailand has suffered months of deadlock since the protest campaign began in November, with at least 27 people killed and hundreds wounded.
