DUBAI, Feb 14 (Reuters) - Emirati bank Mashreq will use a transaction monitoring tool for correspondent banking developed by Israeli cyber security firm ThetaRay to detect financial crimes, the companies said on Monday.

The value of the deal was not disclosed.

Mashreq, which in the past has paid millions of dollars to the U.S. over sanctions violations, said ThetaRay's technology allowed banks to "effectively thwart financial crime risks in the increasingly complex space of cross-border payments."

The United Arab Emirates, the region's trading capital, has tightened banking and financial regulations in recent years; urging banks to increase anti-money laundering-efforts.

ThetaRay, which uses artificial intelligence to identify financial cyber threats such as money laundering or banking fraud, said Mashreq was its first Emirati customer. The UAE and Israel established ties in 2020.

Mashreq last year agreed to pay $100 million in penalties to resolve a U.S. government probe into violations of sanctions against doing business with Sudan.
