Colombian foreign ministry declared their decision to give citizenship to dozens of Venezuelans who have separated from their Colombian spouses or parents after the border crisis.
Foreign Minister Maria Angela Holguin said at least 158 Venezuelans who were in uncertainty will reunite with their families, of whom they have been separate for two weeks.
Over 1,100 Colombians have been deported by Venezuelan government and over another 10,000 people left in fear of reprisal during the last two weeks.
The crisis emerged as Venezuelan President Nicolas Maduro ordered two main border crossings to close, following an attack on a military patrol by unidentified assailants.
Maduro had later accused Colombia of waging "an attack on Venezuela's economy," referring to large numbers of smuggling in the border.
Colombian President Juan Manuel Santos has promised to redouble his efforts to “denounce Venezuela's mistreatment of Colombian migrants” on TV late on Tuesday, as his efforts for a meeting of the Organization of American States (OAS) failed.
Santos called diplomats in Colombia to join Tuesday’s cabinet meeting and listen first hand from the migrants living in one of the shelters in the border.
In addition, Holguin will visit Geneva and New York to meet the United Nations' High Commissioner for Human Rights and UN Secretary General Ban Ki-Moon next week.
OAS votes on Santos’ proposal had resulted negatively on Monday, with 17 of 34 votes in favor, one less than the needed number.
Union of South American Nations (UNASUR) meeting on the crisis, on the other hand, was postponed due to Venezuelan Foreign Minister Delcy Rodriguez’s visits to Asian countries.
