Customs and Border Protection officials have arrested 31 illegal immigrants who were smuggled into the U.S. in two separate boats.
The first boat, a fishing panga, crossed the international boundary heading north early Monday morning and came ashore near the mouth of the Tijuana River.
Agents arrested 11 Mexican citizens and 1 Honduran on shore, while the boat returned to Mexican waters.
A couple of hours later, another panga boat dropped 17 people off on a Camp Pendleton Marine Base beach. Thirteen men and four women headed toward the cliffs nearby but agents intercepted them.
The Mexican citizens were arrested.
