Jan 11, 2019 - India is currently in the process of building the world's longest border wall along their 2,500 mile border with Bangladesh. The wall is made of double-fence barbed wire and requires a police force of 70,000 to guard it. The main point of these intense security measures is to keep Bangladeshi immigrants out of India.

Ahmed said as India has already raised fence along 79 per cent of the Indo-Bangla border, it "indirectly helps" his country in checking cross-border crimes.

• Morocco: A 1,700-mile sand wall fortified and surrounded by millions of land mines was built by Morocco in 1975 along disputed, ungoverned territory on its border with Western Sahara.

Melilla sits on the north coast of Africa, surrounded by the waters and territory of Morocco. For the ceaseless tide of African and Asian migrants working their way northwards, it has a compulsive attraction: by accident of military conquest more than 500 years ago, this city which is geographically African is legally part of Spain. As the migrants reach the Mediterranean, where so many of their predecessors have died, Melilla offers them a safe bridge into Europe – if they can smuggle themselves across its barricaded perimeter.                                                                                                                   The Ceuta-Morocco border fence, as seen from Ceuta.                                                                                                                                                                                                                                                                          https://www.theguardian.com/world/2010/apr/17/melilla-migrants-eu-spain-morocco                                               

• Spain: More than two decades ago, the Spanish government built 20-foot concrete barriers to wall off Melilla and Ceuta, Spanish-administered enclaves in Morocco since the 15th century, to increase border security against African migrants.

Spain built fences 20 years ago to keep migrants away. Here's how that worked out
