After an hour-long meeting today, the BNP-led 18-party opposition alliance said it would observe the strike on November 10, 11 and 12.
BNP acting secretary general Mirza Fakhrul Islam Alamgir said the opposition hoped the government would meet their demand of holding the election under a caretaker government within the stipulated time.
"Otherwise, we will be bound to take tougher programmes after the end of the (next) hartal," Alamgir told reporters.
The announcement came a day after the Election Commission said the BNP's right-wing ally Jamaat-e-Islami cannot participate in the next polls in line with a court order.
