As per the Indira-Mujib pact of 1972, no permanent structure can be built within the 150 yards of the border.
In 1975, a guideline for the management of the 4000-km-long Indo-Bangla border was formulated by the two countries which also agreed not to construct any permanent structure within the 150-yard limit.
Similarly, many schools and public buildings in several villages also fell within this demarcation.
"Following India's request, the Bangladesh government has agreed to allow construction of fencing on Zero-Line in some parts of the state," Tripura Home Secretary Manoj Kumar said.
Fencing in the Sabroom sub-division of South Tripura district, which was suspended for quite some time following objections from the Bangladesh Border Guards, would be started soon, he said.
While fencing on the Zero Line at Mohanpur in West Tripura district and Kailashahar in the newly-formed Unakoti district had almost been completed, work at Kamalasagar in Sipahijala district and Belonia in South Tripura district would be started soon.
The state government had identified some areas where erection of fencing 150 yards away from Zero Line would not be feasible and as such approached the Centre to seek permission from Bangladesh.
About 75 per cent of the 856-km Indo-Bangla border in Tripura has so far been completed and the remaining part would be completed by the end of this year, BSF sources said
