The European Union says it is gravely concerned about the fate of Burma's detained opposition leader Aung San Suu Kyi.
In a statement from its headquarters in Brussels, the EU says it is disturbed by reports that Aung San Suu Kyi may be on a hunger strike. It says the government of Burma must be responsible for her health and welfare.
The European Union is among several groups expressing concern for the opposition leader.
Speaking in Tokyo, former U.S. president and Nobel laureate Jimmy Carter said all Nobel winners strongly support the freedom and proper political role of Aung San Suu Kyi. She won the Nobel Peace Prize in 1991.
On Thursday, the U.S. State Department called on Burma to allow international access to Aung San Suu Kyi, to determine whether she is on a hunger strike. Rangoon denied she is refusing food.
Burmese authorities detained Aung San Suu Kyi in late May following an outbreak of violence between her supporters and a group backed by the military government.
Thailand's Foreign Ministry says information it has received suggests the opposition leader is not on a hunger strike. A spokesman declined to reveal the source of the information.
