The British government warned of a heightened risk of terrorist attacks and unrest tied to Indonesian rallies against a proposed fuel price increase.
The British Foreign and Commonwealth Office said it anticipated nationwide protests in Indonesia in response to a fuel price increase set to go into force April 1.
"Public sentiment toward this proposal is highly volatile," the warning read. "You should exercise caution at all times wherever you are in Indonesia and stay away from demonstrations, which will be heavily guarded by police."
A workers' union in Indonesia said it expected at least 25,000 people to attend the April 1 rallies, The Jakarta Globe reports. Police in Jakarta have deployed more than 10,000 security personnel, including in areas near the presidential palace, in response, the newspaper adds.
British nationals, the government advised, should stay away from public demonstrations.
"Terrorist groups continue to plan attacks and have the capacity and intent to carry out these attacks at anytime and anywhere in the country," the warning read. "Attacks could be indiscriminate, including in places frequented by expatriates and foreign travelers."
