Britain says Qatar has agreed to buy 24 Typhoon fighter jets manufactured by the U.K's BAE Systems.
The U.K. defence ministry says an agreement was signed Sunday by Defense Secretary Michael Fallon and his Qatari counterpart, Khalid bin Mohammed al-Attiyah.
Fallon says the deal heralds "even closer defence cooperation" with a strategic partner.
The value of the sale was not disclosed. CMC Markets U.K. analyst David Madden said it was "likely to be in excess of 1 billion pounds ($1.35 billion)."
BAE shares rose more than 3 percent Monday to 614.5 pence.
