US Border Patrol agent shot dead in Arizona, another wounded

A US Border Patrol agent was shot dead and another wounded when they came under fire on Tuesday while responding to a tripped ground sensor in a drug smuggling corridor in Arizona near the border with Mexico, authorities said.

Authorities said three agents were on foot about 5 miles (8 km) north of the border in rocky terrain when gunfire erupted well before daybreak, but provided few additional details on the circumstances of the violence. (Reuters)
