US rejects Mexico’s request for water as Trump opens new battle front

State department turns down special request to supply city of Tijuana in drought-affected north for first time ever

The United States has refused a request by Mexico for water, alleging shortfalls in sharing by its southern neighbor, as Donald Trump ramps up a battle on another front.

The state department said on Thursday it was the first time that the United States had rejected a request by Mexico for special delivery of water, which would have gone to the border city of Tijuana.
