A shadowy group of militant football fans who have largely laid low since they participated in mass anti-government protests in 2013 that led to the military ouster of Egyptian President Mohammed Morsi have claimed responsibility for a car bomb near a Cairo security building that injured at least six policemen late on Aug. 19.

A car bomb wounded six Egyptian policemen on Aug. 20 as it exploded in front of a police building in Cairo, the interior ministry said, the latest in a wave of militant attacks that has rocked Egypt.

A car bomb targeted a state security building in northern Cairo early on Thursday, injuring six Egyptian policemen.

The explosion, which occurred in the Shubra district, destroyed the facade of the building., Al Jazeera informs.

At present, no group has claimed responsibility for the attack, the BBC reports.

The Arab League called Aug. 18 for an "urgent" Arab strategy to militarily back Libya's government against Islamic State of Iraq and the Levant (ISIL), but stopped short of endorsing air strikes against the jihadists.

Polish Airlines (LOT) and Turkish Airlines (THY) inked a letter of understanding to initiate enhanced cooperation on Aug. 13, Turkish Airlines has said in a statement.

Croatian Foreign Minister Vesna Pusic on Thursday said that Croatia's role in the global alliance against the Islamic State was not a factor behind ISIS's - unconfirmed - killing of Tomislav Salopek.

Croatian Prime Minister Zoran Milanovic on Wednesday afternoon said Croatia could "not confirm with complete certainty that Tomislav Salopek was executed by ISIS" though he suggested it was certainly possible.

The reported execution of Croatian worker Tomislav Salopek on Wednesday adds to the grim tally of Western hostages that ISIS has subjected to the barbaric medieval practice of beheading. 

The ISIS militant group has released a video claiming to show the beheading of Croatian hostage Tomislav Salopek. The Croatian man was captured by members of the extreme Islamist group on July 22 outside Cairo. ISIS had threatened to kill the 30-year old man, if some Muslim prisoners were not released by the Egyptian authorities.

The Islamic State of Iraq and the Levant (ISIL) claimed on August 12 to have beheaded a Croatian hostage abducted in Egypt, posting a purported picture of the victim's body on ISIL-affiliated Twitter accounts.
