The US state of department has warned that the Somali terror group al-Shabaab may be planning to carry out attacks in Burundi, which has troops in war-ravaged Somalia.
A statement from the ministry called for the Burundi authorities to be on alert on possible terror attacks.
The statement also advised US citizens not to travel to the East African nation and warned the Embassy officials in Bujumbura not to go out during night hours.
It is believed that al-Shabaab wish to attack the country because Burundian troops are part of a coalition of African Union (AU) forces which are battling the group’s insurgency in Somalia.
The al-Qaida linked al-Shabab insurgents have claimed recent attacks in Kenya,Uganda and Djibouti, who also sent peacekeepers to Somalia.
The group have lost a string of key towns and ports in recent months to 22,000-strong AU force, which fights alongside government troops.
Earlier this month, US officials also warned of potential terror attacks to be carried by the groups in Addis Ababa, Ethiopian capital.
