Security forces have begun deploying across Bangladesh's capital, Dhaka, to ensure peace during a regional summit set to open on Saturday.
Officials say some 30-thousand personnel will provide security during the meeting of the South Asian Association for Regional Cooperation (or SAARC).
The summit comes after a series of bomb attacks blamed on Islamic militants in Bangladesh, who have threatened more attacks on government sites in some areas.
The two-day summit will bring together leaders of Bangladesh, Bhutan, India, the Maldives, Nepal, Pakistan and Sri Lanka. Bangladeshi officials say talks will focus on poverty reduction, economic cooperation and terrorism.
The summit was postponed in January, following the tsunami, and again in February when India withdrew citing the security situation in Bangladesh and the political crisis in Nepal.
