Protests have spread across the Muslim world over the publication in Europe of cartoons of the Prophet Muhammad.
In Indonesia, protesters pelted the lobby of the Danish embassy with eggs and burnt Denmark's flag in the street.
Effigies of the prime minister of Denmark - where the cartoons were first published - were burnt in Pakistan.
Iraqi, Egyptian and Palestinian Islamic groups have called for further demonstrations as Muslims attend Friday prayers.
Palestinian gunmen surrounded EU offices in Gaza to demand an apology from the countries publishing the cartoons.
Many shopkeepers are backing a Muslim boycott of Danish goods that has led to a damaging slump in some firms' sales.
The caricatures have aroused strong emotions because Islamic tradition bans depictions of the Prophet or Allah.
Danish Prime Minister Anders Fogh Rasmussen is to meet ambassadors from Muslim countries to try to calm the row.
