GAZA, Dec. 11 (Xinhua) -- Hamas authorities on Tuesday ordered telecommunication companies, mobile stores and internet providers to stop offering services obtained from Israel.

In a statement, the ministry said offering services from Israeli companies is banned, especially 3G and WiFi services.

Hamas justified its decision that the Israeli internet providers allow access to pornographic websites, which local internet companies in Gaza blocked upon an earlier order from Hamas.

The statement added that the decision also aims at protecting Palestinian telecom companies from "the unfair competition with the Israeli companies."

In Gaza, there is only one mobile operator, Jawwal, which does not offer 3G internet service.
