From the Mail & Guardian:
The Moskovski Komsomolets newspaper reported that Alkhanov had banned Kadyrov from bringing more than two of his private army with him into meetings. It reported that Chechen Prime Minister Ramzan Kadyrov had rung President Alu Alkhanov and given him 30 minutes to flee the presidential administration as his men wanted to storm it. Both sides called for reinforcements and there was further shooting before the situation was defused. Kadyrov later rang Alkhanov to apologise, the paper said.
An aide to Kadyrov played down the clash, saying Kadyrov had attended the meeting. “It was simply a fight between two young sporty guys who don’t know how to use their energy and so had a fight,” he said.
