The Israeli army has arrested 13 United Nations employees on suspicion of terrorist activities.
Army officials Tuesday said charges will be brought against the 13. But they did not provide specifics.
The arrests come after Israel complained to the United Nations, saying Palestinian militants were using U.N. ambulances to transport weapons.
U.N. Secretary-General Kofi Annan launched an investigation into those accusations late Monday. The head of the U.N. Relief and Works Agency for Palestine, Peter Hansen, rejected the Israeli accusations as deliberately inciteful and as propaganda.
