BANGKOK (AP) — Thailand’s caretaker government says it will increase security to prevent clashes that could arise between the two sides in an escalating political crisis.

In a televised announcement Sunday, the government’s security committee warned people to stay away from protest sites for their own safety.

The announcement did not specify what measures would be taken. It came as pro-government and anti-government protesters held competing rallies in Bangkok over the weekend.

The two groups were several kilometers (miles) apart, but concerns of violence have risen following a court’s ouster of Prime Minister Yingluck Shinawatra on Wednesday.

Two people were injured late Saturday when unknown assailants fired two grenades at the prime minister’s vacated office compound, where anti-government protesters were camped.
