The U.S. has announced another round of sanctions targeting several individuals and companies it accuses of generating funds for Hezbollah's operations by helping the terror group evade existing financial restrictions.

The Biden administration also announced sanctions against three individuals allegedly involved in the production and trafficking of captagon, a synthetic amphetamine-type stimulant that it says "harms communities and countries across the region and beyond and is a source of funding for the Syrian regime and its backers," which include Hezbollah.

"The United States is steadfast in our commitment to disrupt Hizballah’s access to the international financial system and its various methods of generating revenue, which the Iran-backed group uses to fund its violence. We will also continue to target the illicit captagon trade in the region, which has become an illicit billion-dollar enterprise operated in part by senior members of the Syrian regime," the administration said in a statement.

At least six people were killed and 43 injured in an Israeli strike on Nabatieh, Lebanon, which hit the town's municipal headquarters during a meeting, according to Lebanese Minister of the Interior Bassam Mawlawi. The city's mayor was among those killed.

"⁠The targeting of the municipality building in Nabatieh occurred during the coordination of relief work and the preparation of aid for distribution to the residents in the cities and villages of the region who are steadfast in the face of the war they are being subjected to and against Lebanon," Mawlawi said in a statement.

Israel's Coordinator of Government Activities in the Territories organization said more than 145 aid trucks entered Gaza on Tuesday and 50 on Wednesday, amid allegations that Israel has failed to facilitate humanitarian relief in the northern part of the strip.

Dozens of aid organizations published a joint statement Wednesday saying no aid has been allowed into northern Gaza since Oct. 1.
