PRAGUE (AP) — Iraq’s prime minister says his country is doing all it can to prevent anyone from supplying weapons to Syria through Iraqi territory.

Prime Minister Nouri al-Maliki says Iraqi troops are deployed near the Syrian border to stop any weapons smuggling and there’s an “absolute ban” on letting any Syria-bound plane suspected of carrying weapons into Iraq’s airspace.

Iraq last month kept a North Korean plane from entering its airspace on suspicion it had weapons for Syria, prompting praise from the US

But US officials have previously accused Baghdad of letting Iran — another ally of Syria — fly weapons to Syrian forces through Iraqi airspace, a charge that Iraq has denied.

Al-Maliki said again during a visit to the Czech capital that such charges are untrue.
