BEIRUT (AP) — The Lebanese militant group Hezbollah this week struck a military post in northern Israel using a drone that fired two missiles. The attack wounded three soldiers, one of them seriously, according to the Israeli military.

Hezbollah has regularly fired missiles across the border with Israel over the past seven months, but the one on Thursday appears to have been the first successful missile airstrike it has launched from within Israeli airspace.

The group has stepped up its attacks on Israel in recent weeks, particularly since the Israeli incursion into the southern city of Rafah in the Gaza Strip. It has struck deeper inside Israel and introduced new and more advanced weaponry.

“This is a method of sending messages on the ground to the Israeli enemy, meaning that this is part of what we have, and if needed we can strike more,” said Lebanese political analyst Faisal Abdul-Sater who closely follows Hezbollah.
