Qatari

The federal lawsuit filed in Los Angeles is the latest action taken by McKillen in his long-running legal dispute with the Qatari royal family, a conflict that has made headlines around the world.

A Qatari official also dismissed the probe as a "smear campaign" against Qatar, which has played a key role as a mediator between Israel and Hamas during the war in Gaza.

Khalil al-Hayyam, the most senior Hamas leader outside Gaza, said the group had approved the draft deal sent by Egyptian and Qatari mediators.

While confirming the talks in the Qatari capital, the Rwandan presidency insisted in a separate statement that direct talks between DR Congo and M23 were "key to addressing the root causes of the conflict".

But Hamas rejected this proposed change to the agreement brokered by US, Qatari and Egyptian mediators, calling it unacceptable.
