Mexico refused to accept a U.S. military aircraft with deported migrants onboard, according to a Reuters reported on Saturday, citing a U.S. official and Mexican official.

President Donald Trump's administration had requested to land a C-17 transport aircraft in Mexico but was denied permission. 

It is unclear why the denial was issued.

Since Trump took office, Immigration and Customers Enforcement (ICE) has been arrested illegal immigrants with criminal records who were released into U.S. communities by sanctuary jurisdictions.
