Hezbollah and Israel traded rocket and missile fire in areas near the Lebanese-Israeli border, officials on both sides said, in the latest flare-up of violence which the United States worries will cause conflict to spiral in the Middle East, Reuters reports.

Hezbollah said it shot down an Israeli drone near the border in the early hours of Saturday. Israel’s military said it intercepted a missile fired at an Israeli drone. The outlet could not verify either statement.

Lebanese officials said an Israeli air strike hit a building in an industrial area near the town of Nabatieh, one of the deepest Israeli strikes inside Lebanese territory since fighting began last month. The Israeli military did not immediately comment on the incident.

Lawmaker Hani Kobeissy distributed a video online of him visiting the site which he said was an aluminium supply store that had been bombed by Israel.
