United Nations Secretary General Kofi Annan says international aid workers helping with tsunami relief have encountered no problems with terrorism so far, despite a security warning.
He spoke to reporters Monday after the Danish government said it had information that terrorists were planning an attack against foreign aid workers in Indonesia's Aceh province, where Muslim separatists have battled the government for decades.
U.N. officials told the Associated Press they have declared a state of heightened emergency while Denmark's warning is investigated.
Meanwhile the death toll from the disaster has risen to around 170,000, after Sri Lanka added more than 7,000 victims to its tally (on Monday).
The December 26th underwater earthquake and tsunami left 38,000 people dead on Sri Lanka -- the second highest casualty rate after Indonesia, where nearly 115,000 are confirmed dead.
