Kuwaiti officials say they have intercepted three booby-trapped parcels sent to journalists in the emirate, a day after another letter bomb exploded.
The editor was away when the explosion happened
The same source in Lebanon sent all four letter bombs, the officials said.
The explosion on Thursday slightly injured the secretary of Ahmed al-Jarallah, editor of the newspaper Al-Siyassa, who has pro-American views.
Post offices in Kuwait - one of Washington's staunchest allies in the region - were on alert after the blast.
The three intercepted parcels were addressed to Abdallah al-Khalaf, secretary-general of the Kuwaiti Writers' Association, and journalists Nasser al-Utaybi of al-Siyassa and Abdallah Muhammad al-Shaykh of the daily newspaper al-Qabas.
The sender's name was Ghassan Sharbel, assistant editor of the pan-Arab daily Al-Hayat, both of whom condemned the apparent attempt to link them with the attack.
"We denounce the use of the paper's and my name to carry out
such loathsome acts against journalists," Mr Sharbel, a Lebanese, told
AFP news agency.
Mr Sharbel said he had did not know why his name was used.
"But it could be because a letter of which I am supposed to be
the sender would not arouse suspicion," he said.
