Bangladesh has joined a new military alliance consisting of 34 mainly Islamic nations to fight terrorism.
Quoting Saudi Arabia’s SPA state media, BBC reported on Tuesday.
The alliance emerged amid international pressure for Gulf Arab states to do more in the fight against so-called Islamic State, says the report.
"This comes from the Islamic world's vigilance in fighting this disease [Islamic extremism] which has damaged the Islamic world," said Prince Mohammed.
"Currently, every Muslim country is fighting terrorism individually... so co-ordinating efforts is very important."
Saudi Defence Minister Mohammed bin Salman said the new alliance would co-ordinate efforts against extremists in Iraq, Syria, Libya, Egypt and Afghanistan. Afghanistan, Iraq and Syria are not in the coalition.
According to the report, a joint operations centre is to be established in Riyadh, the Saudi capital.
Countries from Asia, Africa and the Arab world have joined the alliance sans Iran, Saudi Arabia's main regional rival.
The list of 34 members is Saudi Arabia, Bahrain, Bangladesh, Benin, Chad, Comoros, Cote d'Ivoire, Djibouti, Egypt, Gabon, Guinea, Jordan, Kuwait, Lebanon, Libya, Malaysia, Maldives, Mali, Morocco, Mauritania, Niger, Nigeria, Pakistan, the Palestinians, Qatar, Senegal, Sierra Leone, Somalia, Sudan, Togo, Tunisia, Turkey, United Arab Emirates and Yemen.
The SPA state news agency said 10 other "Islamic countries" had expressed support, including Indonesia.
Prince Mohammed said: "These countries have procedures to go through before joining the coalition, but out of keenness to achieve this coalition as soon as possible, [the alliance of] 34 countries has been announced."
In announcing the coalition, SPA stated that Islam forbids "corruption and destruction in the world" and that terrorism represents "a serious violation of human dignity and rights, especially the right to life and the right to security".
Saudi Arabia is part of the US-led coalition against IS and is also leading a military intervention in Yemen against Shia Houthi rebels.
