The Security Council unanimously adopted the resolution 1137 on September 28, 2001, urging all UN member-states to sign the conventions for a global combat against international terrorism.

Prime Minister Khaleda Zia's cabinet on Monday approved a foreign ministry's proposal moving the eight antiterrorism instruments.

Earlier, Bangladesh had ratified three conventions relating to terrorism, now raising the total number to 11.

"Bangladesh gives a strong and positive signal to the international community about her unalloyed commitment to the war on terrorism by approving these conventions," Foreign Minister M Morshed Khan told the news agency.

With these, Bangladesh approved 11 of the 12 UNSC conventions. The foreign minister said the government will soon approve the 12th one relating to the financing of terrorists.

A subcommittee headed by the finance secretary is working on it and it will be signed shortly, Khan said.

In reply to a question, he said the existing Criminal Procedure Code (CrPC) will be amended to fit with the UN antiterrorism conventions endorsed by the cabinet.

"We have decided to bring about necessary changes to criminal acts to identify both internal and international terrorist acts, resist and control," he said.

The foreign minister will sign the documents and send them to the UN Security Council shortly.

The antiterrorism conventions are convention against taking hostage, convention on suppression of terrorist bombing, convention on punishment of crimes against internationally protected persons, including diplomatic agents, convention on unlawful acts against the safety of fixed platforms located on the continental shelf, convention on suppression of unlawful acts of violence at airports serving international civil aviation, convention on the marking of plastic explosives for the purpose of detection, convention on physical protection of nuclear materials, and convention on suppression of unlawful acts against the safety of maritime navigation.

Earlier, Bangladesh had ratified three antiterrorism conventions--convention on acts committed on board aircraft, convention on suppression of unlawful seizure of aircraft, and convention on suppression of unlawful acts against safety of civil aviation.
