Last week's deadly attack on a mosque in Kuwait has triggered a massive crackdown on Islamist militants, with two police officers joining the ranks of those who have been arrested in connection with the brutal bombing.

Kuwaiti security forces have found weapons, ammunition, maps and slogans that suggest support to the Islamic State during a raid on the home of another suspect in the incident. The suspect then stated that the pro-ISIL paraphernalia, as well as the weapons, were acquired from the officers, according to Reuters.

The attack on Friday left 26 dead, further injuring 227 others. The Islamic State's Saudi Affiliate, the Najd Province, has claimed responsibility for the attack, further identifying the assailant as Abu Suleiman Al- Muwahhid.

Kuwait's interior ministry later identified the attacker's real name, Fahad Suleiman Abdulmohsen Al-Gabbaa, a Saudi, and stated that he entered the country at dawn on the day of the mosque bombing, The Kuwait Times reported.

Authorities have been in high gear since the deadly incident, detaining about 90 people as of date. Ten of the suspects, which include Saudis, Kuwaitis and stateless residents, have been endorsed to the public prosecution. Such a move by the authorities suggests that a criminal case against the suspects has already been opened.

Among the 10 are five principal suspects, who are accused of helping the suicide bomber carry out the attack.
