April 15 (UPI) -- Delegations from Lebanon and Israel have concluded negotiations in Washington, the first diplomatic talks between the neighboring countries in decades as they seek an end to their ongoing conflict.

Israel has for years been in conflict with Iran-backed Hezbollah in southern Lebanon, but it has increased its offensive amid its war with Iran.

Confusion has hung over the war in Lebanon after a cease-fire was called last week, with Pakistan and Iran saying the truce included Beirut, but Israel and the United States claiming otherwise.

The trilateral meeting between Lebanon, Israel and the United States in Washington on Tuesday was "productive," State Department Deputy Spokesperson Thomas Pigott said in a statement after the talks were concluded.
