Turkey's ex-president Abdullah Gul has broken a months-long silence to call for greater democracy, in an apparent message to his strongman successor Recep Tayyip Erdogan, a report said Friday.

Gul -- who had not spoken about politics since he handed over the presidency to Erdogan in August -- also suggested Turkish leaders should adopt a less confrontational style in politics.

Turkish President Recep Tayyip Erdogan on Friday postponed a planned trip to Somalia in order to attend the funeral of Saudi Arabia's King Abdullah, official media reported.

Erdogan is currently on a tour of Africa and was due to travel later Friday to Somalia, where Turkey is a major investor, in what was to be a rare visit by a foreign leader to the war-torn nation.

At least five people were killed Thursday in a suicide car bombing against a hotel in Mogadishu on the eve of a visit to the Somali capital by Turkey's president, police said.

Sources at the hotel, situated close to the heavily-fortified presidential palace, said there were around 70 members of a Turkish delegation in the hotel at the time, but none of them were killed or seriously hurt in the blast.

Turkish President Recep Tayyip Erdogan on Wednesday called on Muslim states to speak with one voice against terrorism and racism, positioning himself once again as a key leader of the Islamic world.

Addressing a meeting of the Organization of Islamic Cooperation (OIC) in Istanbul, Erdogan said Islamic states had to defeat the successors of the iconic British officer Lawrence of Arabia who were seeking to disrupt the Middle East.

Turkey's ruling party was Wednesday shaken by a rare rebellion by its lawmakers in a key late night vote on whether to send to trial four former ex-ministers accused in a 2013 graft investigation.

The Turkish parliament voted against putting the ministers on trial, drawing a line under a scandal that shook President Recep Tayyip Erdogan's government.

A missing South Korean teenager suspected of joining the Islamic State group had a twitter account, "Sunni Mujahideen," on which he tweeted his desire to enrol with the militant group, police said Wednesday.

The 18-year-old middle school dropout, identified only by his surname Kim, went missing in Turkey earlier this month, and there is speculation that he crossed into Syria.

On grainy Istanbul airport security footage, she is shown entering the country like any tourist. A week later, she is in Islamic State-controlled Syria, without ever being apprehended.

How was Hayat Boumeddiene, the fugitive partner of one of the Paris attackers, able to cross through Turkey into Syria so easily?

The British and Turkish prime ministers held talks Tuesday on how to deal with the threat posed by Islamic State (IS) militants.

It was the second meeting in just over a month between British Prime Minister David Cameron and his Turkish counterpart Ahmet Davutoglu in London.

Turkish Prime Minister Ahmet Davutoglu on Tuesday called for a "new beginning" in relations between Turkey and Armenians scarred by a bitter historical dispute over mass killings during World War I.

"We call on all Armenians, and invite all those who believe in Turkish-Armenian friendship to contribute to a new beginning," Davutoglu said in a statement marking the eighth anniversary of the murder of Turkish-Armenian journalist Hrant Dink, who campaigned for reconciliation between the two neighbors.

Turkey on Tuesday arrested 23 people, including former senior officials in its telecoms and science agencies, in a new wave of raids against suspects accused of wire-tapping senior officials including President Recep Tayyip Erdogan.

The official Anatolia news agency said prosecutors issued warrants for 28 people in Ankara, Istanbul and other cities, with those arrested former employees of the telecommunications agency TIB and the TUBITAK science and technology agency.
