Russia’s federal agency for tourism, Rostourism, recommends the Russian nationals visiting Indonesia to be vigilant and not to leave guarded resort areas, the authority’s press service said on Friday following the terrorist attacks in Indonesia’s Jakarta a day earlier.

"The Russian Foreign Ministry and Rostourism reiterate their recommendations to Russian nationals leaving for Indonesia to be vigilant, to stay away from crowded places and not to leave the protected resort areas without any urgent need," the tourist authority said in a statement.

On Thursday, representative of the Russian Foreign Ministry Maria Zakharova said addressing to Russian tourists: "in cases of emergency, it is necessary to contact the Russian embassy in Indonesia. The contact phones are available on the Russian Foreign Ministry website and the website of our embassy in Jakarta." 

Seven people, including five attackers, died in a series of explosions and a shootout that took place in the center of Jakarta, the capital of Indonesia, earlier on Thursday. Over 25 people were injured, including citizens of Austria, Germany and the Netherlands. No information about Russians has been reported.

The Islamic State (IS) terrorist organization has claimed responsibility for the explosions.
