The government has blocked popular internet calling and messaging services Viber and Tango on security grounds.
Bangladesh Telecommunication Regulatory Commission (BTRC) has sent letters to the mobile phone operators and international internet gateway operators regarding the closure.
BTRC Secretary Sarowar Alam confirmed the Dhaka Tribune about the decision.
He also confirmed that it was a short-term decision and therefore will not be continued for a long time.
The notice was also sent to several embassies in Dhaka informing that the service will be inactive from 12am, Sunday to 6pm.
Later, the duration of the closure was extended till 12am on Monday.
Sources said the BTRC has recently got a letter from a high profile intelligence agency which warned that militants are using different modern services with the help of 3G.
“Terrorist groups, militants and anti-state elements are carrying out terror and subversive activities using the facilities of communication devices such as mobile phones and Internet technologies such as Viber, Skype, Tango and WhatsApp,” the letter reads.
Copies of the letter, sent to the BTRC in the last week of December, were sent to the state ministers for home and ICT asking them to take necessary actions. The BTRC however denied receiving any such letter.
