BEIRUT (Reuters) - Syrian President Bashar al-Assad said on Saturday the main impediment to investment in the country was money stuck in ailing Lebanese banks.

       He said some estimates suggested $40 billion or $60 billion of Syrian funds were stuck in Lebanon.

       In a speech after being sworn in for a fourth term, Assad also said Syria would continue working to overcome difficulties caused by Western sanctions imposed over its decade-long war.
