The Tajik government says a banned Islamic group is behind the weekend's attack on a group of foreign cyclists which left four people, including one Dutchman, dead and three in hospital.
The post said that a "detachment from the soldiers of the Caliphate" launched to strike "citizens of Crusader coalition countries", running them over and then using knives, killing four and wounding four others.

Authorities in the ex-Soviet republic in Central Asia were considering an extremist plot among the possible motives for the attack, the country's interior minister said.
Thousands of people from the mainly Muslim region have joined Islamic State militants in recent years.
Two suspects in the case were killed after they "resisted arrest" and a further four have been detained, the minister said.
Three tourists were also injured by the auto, whose occupants then drove off. Three others, from Switzerland, the Netherlands and France, were injured but are in a stable condition. One sustained a knife wound and was receiving medical assistance.
In Tajikistan, four foreign tourists were killed on Sunday while cycling along a road inKhatlon Province.
Four people were killed by a gang that rammed a vehicle into a group of seven tourists making a cycling tour of Tajikistan and one of the attackers got out and stabbed the injured victims. A Swiss woman was injured by assailants armed with knives and guns.
"The Embassy commends Tajik authorities on their professional and quick response to the incident, and we will continue to work closely with them on the ongoing investigation", the statement added.
During the morning news conference in the Tajik capital, Dushanbe, Rakhimzoda said one of the suspects has been killed. Five attackers were involved in the incident, Tajik officials said earlier Monday.
The IRPT was banned by Tajikistan in 2015 after it was accused of attempting a coup.
The U.S. Embassy said it could not name the two U.S. victims due to privacy concerns, but indicated that it also considered the incident to be an intentional attack. Party leaders now in exile have denied those charges and said the move against them aimed to consolidate the grip of President Imomali Rakhmon, in power since 1992, the second longest-serving leader of an ex-Soviet state.
