China on Tuesday warned its citizens not to travel to Sri Lanka in the near term after a series of explosions there on Easter Sunday.

A spate of bombings on churches and hotels in Sri Lanka killed 290 people and wounded more than 500 others on Sunday. The capital of Colombo is currently under a state of emergency amid warnings of further attacks.

On Tuesday, the Chinese embassy warned its citizens in Sri Lanka to stay away “in the near term” from crowded areas and pay attention to safety reminders.

“If Chinese citizens insist on going after the reminder is issued, it will bring huge security risks to the parties and make it difficult for the embassy to provide effective assistance,” the advisory said in Chinese.

The U.S. State Department on Sunday issued an advisory that Americans should “exercise increased caution” in Sri Lanka. “Terrorist groups continue plotting possible attacks in Sri Lanka,” said the advisory, which cited tourist locations, markets, hotels, clubs and restaurants among possible targets.
