Federal officials have logged more than 1.1 million apprehensions at the U.S.-Mexico border this fiscal year, after another busy month in June, Customs and Border Protection said in a news release Friday.

Many who were taken into custody have attempted to cross the border more than once, officials said.

Apprehensions last reached the 1 million milestone in 2006. But far fewer attempted to cross that year during the searing-hot summer months, when the journey across the Rio Grande or vast ranches is especially dangerous. Approximately 68,000 migrants were taken into custody in June 2006 — compared with 188,829 apprehensions last month, which was a 5 percent increase from May.
